11/16/2020 – Ephemeris – How to find the Pleiades or Seven Sisters

November 16, 2020 Comments off

This is Ephemeris for Monday, November 16th. Today the Sun will be up for 9 hours and 31 minutes, setting at 5:13, and it will rise tomorrow at 7:43. The Moon, 1 day past new, will set at 6:31 this evening.

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. When I was nearsighted*, though corrected, I never had been able to see more than a few stars and a bit of fuzz. However, with binoculars, even I could see over a hundred stars appear along with the dipper shape of the brightest. The fuzz I saw was unresolved stars, but in photographs the Pleiades actually contain wisps of the gas and 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 as they disappear in the west in evening twilight next spring.

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

*My vision was corrected with cataract surgery a few years ago. The Pleiades now have a granular appearance now.
