It's Zubenelgenubi and Zubeneschamali Time Once Again!

A look at Scorpius, Zubeneschamali and Zubenelgenubi about 1 1/2 hours after sunset. The Scorpion's brightest star, Antares, is far brighter than Zubeneschamali today. 2000 years ago the two stars were equal in brightness.

A good set of binoculars or a small telescope will split Zubenelgenubi into two stars. The brighter of the two stars in this image is itself composed of two stars, but they are too close together to separate into distinct objects, even with a very powerful telescope.

ubenelgenubi lies very close to the path of the moon and sun, and is sometimes covered by one of them. This is called an occultation.
