11/21/2022 – Ephemeris – The Pleiades or the Seven Sisters

November 21, 2022 Comments off

This is Ephemeris for Monday, November 21st. Today the Sun will be up for 9 hours and 21 minutes, setting at 5:09, and it will rise tomorrow at 7:49. The Moon, 2 days before new, will rise at 6:10 tomorrow morning.

A marvelous member of 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. 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 currently passing through. In Greek mythology, the sisters were daughters of the god Atlas. I’ll be revisiting the Pleiades several times this autumn, winter, and before they disappear in the west in evening twilight next spring.

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.

Pleiades finder animation for 8:30 pm tonight, November 21, 2022. Mars is the interloper this year, seen between the horns of Taurus the Bull. The V of stars that make up the face of Taurus the bull is a star cluster of stars called the Hyades. In Greek mythology, they are the half-sisters of the Pleiades. Created using Stellarium, LibreOffice Draw, and GIMP.

The Pleiades, about what you'd see in binoculars.

The Pleiades, about what you’d see in binoculars. To the naked eye, six or seven stars might be glimpsed. As star clusters go, it might seem small and unremarkable, but the Pleiades is nearby, and the brightest star cluster visible. Its stars are regarded by cultures around the world as female stars, generally sisters.  Credit: Mine.
