09/18/2017 – Ephemeris – The constellation of the shield

September 18, 2017 1 comment

Ephemeris for Monday, September 18th. The Sun will rise at 7:25. It’ll be up for 12 hours and 21 minutes, setting at 7:46. The Moon, 2 days before new, will rise at 6:35 tomorrow morning.

In the evening sky, in the south after it gets dark can be seen part of the Milky Way. There is actually a constellation here located between Sagittarius the archer, which really looks like a teapot, below and Aquila the eagle above. It’s Scutum the shield of John Sobieski the Polish king who stopped the advance of the Turks at Kalenberg in 1683. Scutum is the only official constellation I know of which is related to a real person. The Polish half of me is very proud. However the stars here are so dim and embedded in the glow of the Milky Way as to be nearly impossible to discern. Scutum lies in one of the richest portions of the Milky Way, wonderful to scan with binoculars and telescopes for star clusters and nebulae or clouds of dust and gas.

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