11/29/2021 – Ephemeris – Orion is rising in the evening sky

November 29, 2021 Comments off

This is Bob Moler with Ephemeris for Monday, November 29th. Today the Sun will be up for 9 hours and 6 minutes, setting at 5:04, and it will rise tomorrow at 7:59. The Moon, 2 days past last quarter, will rise at 3:07 tomorrow morning.

In the east, the central winter constellation Orion the hunter throws a leg over the horizon between 8 and 9 p.m. as Robert Frost told in his poem Star-Splitter. The upright rectangle that is his body on December evenings is tilted to the left as he rises, with a bright red star Betelgeuse at the top left of the rectangle, his shoulder. At the opposite corner is blue-white Rigel, a knee. In the center of the rectangle is a line of three stars nearly vertically aligned as he rises, which represents Orion’s belt. The Anishinaabe native peoples of this area call him the Wintermaker. His rising in the evening heralds the coming of winter.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EST, UT – 5 hours). They may be different for your location.
