In the Night Sky

August 2016

The Planets: Jupiter, Venus and Mercury are playing around each other as they sink slowly in the west, while Mars and Saturn are taking time around the head of Scorpious. The ‘ Big Five’ are brightly in the sky.

The glorious full moon came about on 18 August then slowly passed to last Quarter on 25 August;

Opening the new month, September with the New Moon and an annual solar eclipse.

Look for Ptolemy’s Cluster also known as Messier 7, near the border between Scorpius and Sagittarius

Fun this month would be taking a good slow look at the Milky Way which spans the sky; from the eastern horizon through  Aquila, Sagittarius through Scorpious almost overhead and down to the southwestern horizon.
