08/18/11 – Ephemeris – The constellation of Scorpius the scorpion

August 18, 2011

Thursday, August 18th.  The sun rises at 6:48.  It’ll be up for 13 hours and 55 minutes, setting at 8:43.   The moon, 3 days before last quarter, will rise at 10:25 this evening.

There’s a large constellation located low in the south as it starts to get dark about 10 tonight  It’s Scorpius the scorpion.  Its brightest star is Antares in its heart, a red giant star, that I get calls about from time to time as being a UFO.  From Antares to the right is a star then a vertical arc of three stars that is its head.   The Scorpion’s tail is a line of stars running down to the left of Antares swooping to the horizon before coming back up and ending in a pair of stars that portray his poisonous stinger.  Scorpius looks huge lying on the southern horizon.  But if you go south Scorpius will be higher in the sky, and will look smaller.  Being close to the horizon from here, Scorpius shares with the rising and setting sun and moon the illusion of increased size.

* Times are for the Traverse City/Interlochen area of Michigan.  They may be different for your location.

Addendum

Scorpius at 10 p.m. tonight from near 45 degrees north.  Created using Stellarium.
