11/03/2016 – Ephemeris – Capricornus, a very strange goat

November 3, 2016 Comments off

Ephemeris for Thursday, November 3rd.  The Sun will rise at 8:24.  It’ll be up for 10 hours and 3 minutes, setting at 6:28.  The Moon, half way from new to first quarter, will set at 9:25 this evening.

The planet Mars is just to the right of the stars of Capricornus, one of the constellations of the zodiac.  Astronomers and others who draw the constellations by drawing lines between stars like a dot to dot puzzle have a hard time getting a sea-goat emerge from its stars.  The sea-goat has the front part of a goat and the back half like a fishes tail.  Kind of like a mergoat, instead of a mermaid.  To me, the constellation looks like a large sagging triangle, just above-left of Mars right now.  It will take Mars only to mid December to cross Capricornus to enter Aquarius, just east of it.   A couple of thousand years ago Capricornus was the location of the winter solstice point in the sky, for which the Tropic of Capricorn was named.  That point is now on the Ophiuchus-Sagittarius border.

09/15/2014 – Ephemeris – The mer-goat Capricornus

September 15, 2014 Comments off

Ephemeris for Monday, September 15th.  The sun will rise at 7:21.  It’ll be up for 12 hours and 31 minutes, setting at 7:53.   The moon, at last quarter today, will rise at 12:21 tomorrow morning.

Nearly 2000 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 any more, Sagittarius, one constellation west and due south at 9 p.m., 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 11 p.m. and tilted a bit from the upper right to the lower left.  The image that is supposed to be represented by the stars is that of a goat whose hind quarters are replaced by a fish’s tail, not a mermaid but a mer-goat.
