The conjunction last Sunday morning

July 18, 2012

In the latest Mount Baldy observing report I described an awesome predawn conjunction of the moon, Venus, Jupiter, and the bright star Aldebaran. What made it so great was not just the close appearance of four bright objects in the eastern sky, but the almost perfect symmetry of their arrangement: not only did they form an almost perfect arrowhead shape, but the arrowhead pointed straight up toward the Pleiades. All in all, just about the most beautiful celestial sight I’ve seen with my naked eyes.

Just as the kite was flying up over the hill to the east of our observing site, a nice couple drove up and set up a camera. They were Robert and Elizabeth Preston, and they kindly send this photo with permission to post. Trust me, you’re going to want to click through to the big version.

Here’s a closeup of the four conjunction objects from a photo by Terry Nakazono. The moon, Jupiter (top), and Venus (bottom) are all unmodified. I had to crop out the area around Aldebaran (right) and boost the contrast to bring out the star.

I can’t imagine a better end to an observing run.
