11/02/2021 – Ephemeris – Finding the Pleiades or Seven Sisters

November 2, 2021 Comments off

This is Ephemeris for Election Day for some, Tuesday, November 2nd. The Sun will rise at 8:22. It’ll be up for 10 hours and 7 minutes, setting at 6:29. The Moon, 2 days before new, will rise at 6:35 tomorrow morning.

A marvelous sight in the autumn skies can be found low in the east after 8 in the evening. It is the famous star cluster called the Pleiades or the Seven Sisters. I might also add the “Tiny Dipper”. Many people can spot a tiny dipper shape in its six or seven stars, and mistake it for the Little Dipper. However, with binoculars, one can see over a hundred stars appear along with the dipper shape of the brightest. In photographs, the Pleiades actually contain wisps of the dust they are passing through. They are a young star cluster, whose age is estimated to be one hundred million years. In Greek mythology, the sisters were daughters of the god Atlas. I’ll be revisiting the Pleiades several times this autumn, and winter, starting on Thursday.

The astronomical event times given are for the Traverse City/Interlochen area of Michigan (EDT, UT – 4 hours). They may be different for your location.
