10/04/2018 – Ephemeris – Capricornus the sea-goat

October 4, 2018 Comments off

Ephemeris for Thursday, October 4th. The Sun will rise at 7:44. It’ll be up for 11 hours and 33 minutes, setting at 7:17. The Moon, 2 days past last quarter, will rise at 3:14 tomorrow morning.

Two thousand years ago the southernmost of the constellations of the zodiac was Capricornus the water goat. That’s why the latitude on the earth where the sun is overhead on the winter solstice is called the Tropic of Capricorn. Not anymore, Sagittarius, one constellation west, has that honor today. Actually, Capricornus does need the press. It’s large but made up of dim stars. To me, it looks like a 45-degree isosceles triangle, long side up, but which all the sides are sagging. The constellation is found low in the south at 10 p.m. with Mars on its western edge. The image that is supposed to be represented by the stars is that of a goat whose hindquarters are replaced by a fish’s tail, not a mermaid but a mer-goat.

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