Triple Planetary Alignment - 2013 May 23

The planets Jupiter, Venus and Mercury were all visible during evening twilight on May 23. Mercury has caught up to Venus and will now climb higher each night. This is part of a several-week-long triple planetary alignment as all three bright planets appear together in the evening sky. The planets will move closer together each night culminating in a conspicuous triangle on the evening of May 26.

In the image above, Jupiter, Venus and Mercury appear from left to right. The figure to the right can also be used to identify the planets on May 23. The Chirichaua Mountains form the horizon.
