Observing Report: Total solar eclipse on August 21, 2017

August 28, 2017

My parents, Norma and John (seated), and me with London and Vicki (standing), with the projected eclipse.

Long Range Planning

Since the August, 2017, eclipse first came on my radar, my plan was to see it from somewhere on the Great Plains. I had two reasons for this. One, most of my family lives in Oklahoma, and it would be simpler for them to drive up to the eclipse path than to fly to somewhere more remote. Also, on the plains you can usually see weather coming from a long way out, and fronts move in predictable ways. I figured that if clouds did spring up on eclipse day, I’d have a better chance of driving to get around them on the plains than anywhere else.

Originally I’d been thinking Kansas or Missouri, both of which border Oklahoma and would have made short drives for my relatives. But a closer look at the eclipse map this spring dissuaded me. The eclipse would only barely clip the northeastern corner of Kansas, in the relatively densely populated area around Kansas City. The path of totality painted a broad stripe across Missouri, but mostly along a line connecting Kansas City and St. Louis. I figured that area would get hammered by visitors, and the cloud forecast wasn’t as favorable as it was for points west, either.

Nebraska, on the other hand, looked pretty good. My maternal grandparents used to live in Imperial, in the southwest corner, and they retired just a few miles down the road to Enders. Imperial would make a convenient rendezvous point, both for any family driving up from Oklahoma, and for me, Vicki, and London flying in from California.

In one sense Imperial was not convenient: it’s a long way from any major airport. Two hundred miles from Denver, and three hundred from Lincoln. But I like long drives in the country (really, I do!), and I was happy to trade some driving at either end of the trip if it would save me traffic in the middle.

I guess now is a good time to mention that I did not want to stay on the path of totality. I figured – correctly, as it turned out – that competition for rooms would be fierce, that at least some places would be gouging visitors, and that traffic would be a problem in at least some areas. Instead, I wanted to stay an hour or two off the path of totality, preferably somewhere out of the way, where crowds would not be a problem, but I’d still have a range of possible observing spots within easy driving range. Again, Imperial was a promising choice, and in early February, I called and reserved rooms for my parents and for Vicki, London, and me at the Balcony House Bed & Breakfast (which was outstanding, by the way – it’s worth going to southwestern Nebraska just to stay there).

By now, plans were firming up. I knew that the fall gross anatomy course at WesternU would be rolling by eclipse time, and Vicki and I would need to arrange things so we’d miss as few days of lab as possible (many thanks to our department chair for the time off!). But we also wanted some time in Imperial to unwind, and to visit places important to our family history. That meant leaving on Saturday, August 19, and coming back on Tuesday, August 22. The Balcony House didn’t have any rooms on Saturday night, and in fact, nobody else in Imperial did, either. So we decided to make Saturday an easy day and only drive as far as Holyoke, Colorado. Holyoke is another old family stomping ground – Grandpa and Grandma had lived there for several years, too, and it’s where my mom grew up.

Sun funnel testing in Claremont

The Sun Funnel Rides Again

Gear! I didn’t settle on exactly what I’d be rolling with until Thursday, August 17, just two days before we were to fly. My old Sun Funnel – veteran of the annular eclipse and Venus transit of 2012 and the partial eclipse of 2014 – was in storage in the garage. There was never really any question but what it would be going along; it’s just too darned useful for showing solar events to even small groups of people. I did have to decide which scope to use with it. We’d sold London’s AstroScan, but my flock of airline-portable scopes had grown in the meantime. Strong contenders included the GalileoScope, Tasco-Vixen 9VR, and SkyScanner 100. I set up and tested the 9VR and the SkyScanner, and I ended up going with the latter scope, for several reasons:

  1. It has the most aperture of any scope I was seriously considering.
  2. It’s at least somewhat collimatable.
  3. With its open design, I wasn’t worried about it overheating.
  4. It balanced the best with the Sun Funnel mounted.

For the flights, I put the SkyScanner in the padded bag that my Apex 127 came in, and packed t-shirts and socks around it. The Sun Funnel I broke down – I put the screen material in a folder between sheets of clean paper, and I stuffed more socks in the funnel itself. I also brought along four pairs of eclipse glasses, a piece of #14 welder’s glass (previously seen here), and 10×42 Bushnell binoculars to look for solar prominences during totality.

One more piece of gear came to me on the road. Sunday morning we woke up in Holyoke, Colorado, had lunch at The Skillet (which had excellent country cooking), and then popped across the street to the Family Dollar for a few odds and ends. I’d been thinking of making a little sun-finder, like the one David DeLano detailed in this post. My SkyScanner has a DIY wooden bracket that is square to the tube, so I just needed something round that I could use to project a spot of sunlight. I ended up going with a $1 empty condiment bottle, which I already blogged about here. When we rolled into Imperial that afternoon, I unpacked all of the gear and did a test run on the sidewalk in front of the Balcony House. Everything was ready – now we just needed clear skies.

Targeting on the Fly

My initial targets for possible eclipse observing spots were the towns of Tryon and Stapleton, Nebraska, both about a half an hour north of North Platte. I picked up a Nebraska road map and highlighted possible routes from Imperial to either Tryon or Stapleton, going either north to the path of totality and then east, or vice versa. Either town would have required about 2.5 hours of driving on a regular day, and I figured it would be smart to budget for eclipse traffic. The east-then-north route to Stapleton had the following problem: it went through North Platte, and if traffic was apocalyptically bad, we might get stuck on the edge of the path of totality, or even outside of it. The north-then-east route to Tryon would get us close to the centerline first, with fewer opportunities to get stuck off the path.

Ah, but then. A few days out, and the weather apps were predicting partial clouds and possibly even rainfall for west-central Nebraska. Right up until Monday morning, North Platte, Tryon, and Stapleton all looked they might get clouded out. So Sunday the five of us – Mom, Dad, Vicki, London, and me – had a council of war. To the level of detail possible in weather prediction, the area around North Platte looked lousy, but Scottsbluff, in far western Nebraska, was supposed to have sunny skies. Between North Platte and Scottsbluff, the weather looked progressively better to the west, and worse to the east. So we changed things up: instead of turning east to Tryon or Stapleton, we’d stay on Highway 61 north out of Ogallala and shoot up to Hyannis, then turn west on Highway 2 and go as far as we needed to find clear skies. This was basically the Tryon plan with the directions reversed: go straight north to the eclipse path first, then drive east or west along the path to a promising destination.

The Drive Up

I wish I had had the time and opportunity to take pictures during the drive up from Imperial. It was beautiful. We left Imperial right after dawn, and the rising sun turned the fields to gold. Within a few miles, we could see banks of fog lying in the low spots on the landscape. And then a few miles further, the fog was lying everywhere. We started driving through fogbanks that congealed into an unbroken blanket by the time we reached Ogallala. The weather apps were still projecting clear skies to the west and, well, unclear skies to the east, so we kept going.

The fog had cleared by the time we saw our first eclipse-watchers, at the fairgrounds in Arthur. There were hundreds of people in RVs, tents, cars, and trucks, looking worriedly up at a sky that was completely socked in with clouds. We kept going, and saw a few hundred more scattered along the side of the road as we approached the center line. About this point we hit what I can barely bring myself to describe as ‘traffic’. At its worst, we were the 9th and 10th vehicles in a convoy of 13, but the convoy was rolling along at a steady 62 or 63 miles per hour, which was fine and certainly not worth the risk of trying to pass someone on a two-lane road in the Nebraska sandhills. The hills themselves were liberally spangled with wild sunflowers. From a distance, they looked like they’d been dusted with pollen. Everywhere we went the landscape was green.

Alliance

From a purely eclipse-viewing perspective, I would have been happy with any of the towns on Highway 2 west of Hyannis. Sure, they were a few miles off of centerline, but the difference in the duration of totality would have been trivial. And I figured we’d miss the big crowds expected at Alliance. But this plan had one fatal flaw, which I did not anticipate: a complete absence of public restrooms west of Hyannis. If I’d been by myself, I might have just pulled over anywhere and, er, recharged the water table as needed, but that’s a less attractive option to a group that includes two women and two senior citizens. Actually, there may have been a public restroom in Lakeside, but we had no chance to find out, as there was a big train blocking the road into town when we came by. So we headed on into Alliance and braced for the worst.

Our setup at the Western Nebraska Community College shindig. The forest of telephone poles in the background is where line repair people train.

The worst turned out to be not that bad, actually. We drove past a big group assembled on a grassy field on the east edge of town, and on to the first gas station that looked like it might have restrooms. By the time we’d all had a biology break, it was almost time for the eclipse to start. We decided to head back out to the east edge of town and see if the group on the grass still had some parking spots. This turned out to be an excellent choice. The parking was organized by the Western Nebraska Community College, which had free porta-potties and eclipse gear for sale. We ended up next to a family from Denver that we had met in line at the gas station. They all had eclipse glasses but no other optics, so I set up the Sun Funnel so they could watch with us, and they returned the favor by taking pictures of our party.

The Eclipse

As soon as we had the cars parked, I was busy setting up the Sun Funnel, while everyone else got folding chairs set up and got their eclipse glasses on. I got the photo above, my first shot of the eclipse, at 10:45 AM.

There was a wind out of the north that kept threatening to snatch our hats away, and it was flirting with blowing the scope over. I can’t remember ever setting up the Manfrotto tripod for low use, with the legs spread almost straight sideways, but I remembered from the documentation that doing so was possible. That fixed the stability issues with the scope, and from that point on, all we had to do was re-aim it every few minutes (I’d already made this switch in the family shot above – that shot is out of order in terms of eclipse phases). As I mentioned in a previous post, not only was the dollar store mustard bottle sun finder cheap and effective, but I could see the projected dot through the translucent walls of the bottle so I didn’t have to get my head behind or underneath it to aim the scope – handy when the sun was almost directly overhead.

A labeled shot from the end of the eclipse, when all six of the big sunspots were visible, with the Earth added for scale. All of the other crud on the image is dirt and bits of grass – that’s what happens when gear is left out in the wind in a grassy field for three hours.

There were half a dozen nice sunspots, and it was fun to watch the moon overtake them. A lot of the people who stopped by to look at the sun funnel weren’t familiar with sunspots, so I gave them the quick spiel: giant magnetic storms on the sun, with the biggest that we could see then being about the same size as planet Earth.

About halfway between first contact and totality, the north wind started pushing clouds across the sky, which you can see in the above video. This added some definite suspense to the proceedings, especially when, about 5 minutes before the start of totality, a huge “dreadnought class” cloud came over. I think everyone on the field was on pins and needles – we could still see the sun, as the next photo demonstrates, but it wasn’t what you’d call a great view.

Fortunately the cloud moved out of the way right at the start of totality. And I mean precisely then. Below is a shot from just a couple of seconds before, with the diamond ring effect haloed by the tail-end wisps of cloud. Those wisps moved out just as the moon covered the last light of the sun, and our view of totality was perfectly clear.

That photo above is my best eclipse shot. Vicki has a DSLR but I didn’t take it along. I did waste a few seconds, but only a few, trying to get a couple of HDR shots with my iPhone, but they didn’t really come out. I had read plenty of horror stories of people who basically missed their first eclipse messing around with cameras, so I resolved long ago that if I was lucky enough to have clear skies for totality, I’d try to spend them looking, not shooting.

For the most part, the partial phases of the eclipse were familiar to me from the 2012 and 2014 eclipses. Totality was a whole ‘nuther beast. This was my first total eclipse, and even though I had read a lot of eyewitness reports and seen some videos of other total eclipses, several things surprised me:

  1. Neither of my previous eclipses had been close enough to total to produce the weirdly sharp shadows that you get on either side of totality, when the thin crescent sun acts more like a point source than a bright extended object. So I’d never seen that effect before, and neither had anyone that I was with. We had fun marveling at our shadows, but I didn’t think to get any pictures or video of them. You can see the sharp shadows starting at 1:25 in this video.
  2. It got a lot darker a lot earlier than I expected. This was especially true in the last 10 minutes before totality. It was extremely weird – before the dreadnought cloud moved in, we were all aware of standing in direct sunlight, just not much of it. It wasn’t like diffuse sunlight coming through clouds, and it wasn’t like sunset light, either. I’ve never seen anything else quite like it – which I guess is part of the reason people chase eclipses, to see things you can’t see any other way.
  3. The inner corona was a lot brighter than I expected. I couldn’t really see any of the outer corona, just a thin bright ring around the moon. It was bright white. The contrast between the blazing white of the corona and the absolute blackness of the moon made the latter even more unearthly. In Seeing in the Dark, Timothy Ferris described the moon during totality as an “awful black ball” and I can now vouch for the accuracy of that description. It doesn’t look right.
  4. Even at the midpoint of totality, the sky was brighter than I had thought it would be, and the ground was darker. We all did look up, and saw Venus, Mars, Mercury, and Regulus, but I didn’t see any other stars; the stars didn’t ‘come out’ as I had expected. In contrast, right where we were, looking around at family members and other eclipse chasers, it was dark, like being outside half an hour after sunset. And the 360-degree twilight lit the horizon all the way around in shades of orange, salmon, pink, and violet. In general, the terrestrial effects of the eclipse were more pronounced and arresting that what was going on in the sky – with the undeniable exception of that awful black ball.
  5. I assume that the atmospheric effects on either side of totality are symmetrical – that the weird light I mentioned above in point 2 extends just as far after totality as before, and that the 360-degree twilight extends just as far before totality as after. But that’s not how I perceived them. I noticed the oddly thin light before totality, and after totality had ended I was surprised at how long the sunset effect persisted. The above photo is from a minute and a half after the end of totality, looking north-northeast, about 90 degrees off the path of the shadow, and the twilight effect is still visible in the distance.

After Totality

Totality was a rush. In the aftermath we sat around talking happily about how amazing it had been, and watching on the sun funnel as the moon gradually uncovered the sun. London and I made pinhole projections – his is above, mine below.

We also wandered around until we found a cottonwood that was projecting crescent suns on the street. Here’s a photo:

And a video – this worked out better than expected, because the wind was blowing the leaves and branches around and making the crescent suns flicker, like sunlight glinting off moving water. Shame I didn’t think to turn the phone sideways, but I’d just had my mind blown, so I’m giving myself a pass.

All too soon it was winding down. The telescope and sun funnel had been the first things set up when we rolled in, and they were the last things put away when we left. Here’s my last shot, from 1:16 PM:

Ironically, after all the gloomy predictions, traffic was worse getting away from the eclipse than it had been getting to it. I’d hoped that maybe we could head south out of Alliance and fast-track it back to Ogallala on Highway 26, but that way was jammed up. So we went back the way we came. On the drive home we were the 5th and 6th vehicles in a train of 17, and we had to settle for a bit under 60 mph, but we still made it back in good time. There was another train blocking the access into Lakeside, so I still don’t know if the town has a public restroom.

The trip had one neat little coda. On the flight home, London had the window seat, and he spotted the young crescent moon, back in the evening sky after its big adventure. I passed him my phone, and he got some great shots. Here’s the best:

What now?

There will be other solar eclipses between now and the next “Great American Eclipse” of 2024, but most of them will happen in other parts of the world, and the chances that I’ll have the opportunity to go see them are slim. Here are the upcoming eclipses and transits that I am hoping to observe in the next decade – as always, assuming the skies cooperate:

  • January 31, 2018 – total lunar eclipse
  • January 21, 2019 – total lunar eclipse
  • November 11, 2019 – transit of Mercury
  • May 26, 2021 – total lunar eclipse
  • May 16, 2022 – total lunar eclipse
  • November 8, 2022 – total lunar eclipse
  • October 14, 2023 – annular solar eclipse
  • April 8, 2024 – total solar eclipse
  • March 14, 2025 – total lunar eclipse
  • March 3, 2026 – total lunar eclipse

That’s a pretty good lineup, I think. For more details on all of these events, see MrEclipse.com.

In sum, the eclipse was awesome, in every sense of the word. I get now why people become eclipse chasers. I’m not quite to the point where I can afford to go jetting around the world to catch every single one, but I will make it to every future eclipse that I can. If you ever get a chance to stand in the path of totality, go.

UPDATE 29 August: Mike’s comment below about Cthulhu reminded me that I needed to post another picture. After I put the diamond ring photo on Facebook, my friend Jarrod posted this modified version, which I can’t unsee. Cower before Ecl, the Dragon of Totality:

Camping and stargazing with a child

May 13, 2011

This started out as a comment, in reply to a question from Saint Aardvark on what it’s like camping and stargazing with a 5-year-old along. It grew in the telling, so I’m making it a stand-alone post. If you have ideas, tips, or tricks for making time outdoors with children easier, please share them in the comments!

I started taking London with me to dark-sky sites last summer, when he was about five and a half. Between July and November we went to Owl Canyon, Joshua Tree Lake, Afton Canyon, and the All-Arizona Star Party, so we basically built out from nearby destinations to farther ones. The hardest part for him initially was the long drive. We always pack him a backpack full of books and magazines. I also have a couple of kid-friendly CDs in the car, and I keep a full-size pillow within his reach so he can lay his head down and take a nap while we’re driving.

Once we get to wherever we’re going, London is usually off exploring and looking for bones or cool rocks near our campsite. He is very good at staying withing line of sight and not wandering more than 100 feet or so from me. My first goals are always to get our camping area squared away first, whether we’re staying in a tent or just sleeping in the back of the vehicle, and then to get a fire going for dinner. It helps to arrive an hour or two before sunset; much earlier and we just end up getting sunburned and waiting for dark, and much later and it’s harder to set up in the fading light.

I can’t overstate how useful–nay, critical–it is that I can trust London to mind himself for 30-60 minutes while I get everything squared away. It really drives me nuts when people say how lucky we are that London is well-behaved. It’s true that he has a naturally gentle disposition, but dismissing his good behavior as luck devalues all of the work that we put into disciplining him, and more importantly, all the work that he puts into disciplining himself. It’s precisely because of the effort we all put into maintaining a civil household that we can enjoy ourselves so much when we’re out of the house; good behavior out in the wild is earned by practice at home. I don’t bring this up to be snooty or a tiger parent. I just can’t stand wimps who are too lazy or passive to discipline their kids. That’s a dereliction of parental responsibility and a huge disservice to the children, who will have to learn discipline later on, the hard way, at someone else’s expense. End of rant.

After dinner I make a comfy spot for London to watch for shooting stars and satellites. This might be the lounge chair, if I have it along, or maybe just a sleeping bag and pillow laid on top of a big piece of cardboard on the ground. Or my lap, in whatever seating is available. Usually he tells me when he is getting sleepy and I get him settled in his bed. If we’re sleeping in the back of the car, I make sure a window or door is open so I can hear him if he calls out. He never has yet, but I think the knowledge that he could call for me if he needed is a comfort. And I just don’t want the car sealed up with him inside, even in good weather. I always set up the telescope as close to the car or tent as I can, so I can keep an eye on him and he can know that I’m nearby.

I want London to enjoy these outings as much as I do. I grew up out in the country and the ready access to wide open, semi-wild spaces had a huge impact on me. It’s not really feasible for us to live in the country, so my substitute is to get London out into nature as often as possible, and to try to facilitate his enjoyment of it. Even on the hardcore stargazing trips, I try to make sure that his interests and desires get at least equal billing with my own. I don’t think that’s indulgent–I’d do the same for a camping companion of any age. In the early evening, he mainly wants to run off the cabin fever from the car ride, do a little solo exploring near camp, and look for interesting things on the ground. (I’ve taught him to recognize venomous spiders, scorpions, and snakes. He’s never found any out camping, but when he was four he correctly IDed a black widow spider that set up shop under one of our plant stands in the living room!) I usually grill hot dogs for dinner and then follow up with s’mores. That makes the fixing of dinner something he can help out with, which keeps him engaged and gives him a sense of accomplishment. After dinner, we look for shooting stars and satellites until he conks out. Then I get in a few hours of solo stargazing.

In the morning, we have breakfast and go for a hike. I’m usually running on 3-5 hours of sleep, so having some caffeine available is a must. For the hike, London gets to choose the route and duration (within reason); he’s on these trips to hike as much as I am to stargaze, and we’re both comfortable with the give-and-take involved. If your little one isn’t into hiking, you might see if there is another outdoor activity that they are interested in, that could be their recreational time the way that stargazing is yours. In talking about our hikes, London and I always call them “adventures” that we “brave explorers” go on, and I think putting things in those terms helped inspire him the first few times out. Now he’s so hooked on hiking I could call them “death crawls” and he’d still be eager to get out there.

One last enticement: on the way home, we stop at a restaurant for lunch, and London gets to choose where we stop. This almost always means McDonald’s, but I can live with it. We bring dinner and breakfast fixings with us, so lunch on the ride home is our only extraneous expense. And it gives London a little something to look forward to at the end of the trip, when everything is over but the ride home.

Ultimately, camping with London is so smooth and enjoyable that it’s often the first choice for both of us for passing a weekend with good weather. It’s cheap, too: hot dogs, s’mores fixings, lunch at a fast food joint and 2/3 of a tank of gas usually add up to less money than we’d have spent over the weekend anyway. And it gets us out of the house and at least into some contact with nature. I hope he grows to love wild places as much as I do; I think the best way to cultivate that love is to help him enjoy his time in nature right now. I hope your own family outings are successful, and even when they’re not, I hope that doesn’t stop you from going. It’s worth it.
