The southern sky is adorned with several jewels this week: the Moon appears high in the southern sky before sunset as a waxing gibbous - a few days past first quarter. Jupiter and Saturn are both visible, as are the bright stars Antares and Spica. The full Moon will be on July 9th.

The bright star Altair (featured in the classic SF film Forbidden Planet) rises in the east followed by the constellation Sagittarius to the southeast. Sagittarius is recognizable by "The Teapot" asterism low on the horizon.

Sagittarius has several interesting deep sky objects to observe using telescopes; something cool you can do with the public during nighttime observing sessions is point to the Teapot's spout and say "that's where center of our Milky Way galaxy is!"

Northwest - 4 AM July 5 2017
