07/10/2018 – Ephemeris – The celestial scorpion

July 10, 2018 Comments off

Ephemeris for Tuesday, July 10th. Today the Sun will be up for 15 hours and 21 minutes, setting at 9:28, and it will rise tomorrow at 6:08. The Moon, 2 days before new, will rise at 4:38 tomorrow morning.

For most of the year I’ve been referencing the constellation of Scorpius the scorpion in passing. Let’s take a good look at this creature. There are no scorpions in Michigan, unless someone imported some. However the one celestial scorpion now seen in the south near 11 p.m. is a beautiful example of one. His heart is the red giant star Antares. Another to the upper right leads to a trio of stars in a bit of a vertical bow. It’s claws extend into the next constellation over, Libra and the stars Zubenelgenubi, near Jupiter and Zubeneschamali, the south and north claws. From Antares the body droops down and curves just at the horizon, before making that distinctive curved tail with two stars at the stinger.

The times given are for the Traverse City/Interlochen area of Michigan. They may be different for your location.

Scorpius artwork closer to how I see it with the claws extending into Libra. I was able to find the image using a Google search, but was unable to find the original source.
