11/11/14 – Ephemeris – Something fishy in the stars

November 11, 2014 Comments off

Ephemeris for Veteran’s Day, Tuesday, November 11th.  The sun will rise at 7:33.  It’ll be up for 9 hours and 45 minutes, setting at 5:18.   The moon, 3 days before last quarter, will rise at 9:41 this evening.

High in the south at 9 p.m. are the four bright stars of the Great Square of Pegasus, the upside down flying horse.  Lying along the left and bottom sides of the great square is the constellation of Pisces the fish, one of the 12 constellations of the Zodiac that lie along the path of the sun, moon and planets.  Even though Pisces is called the fish, the fish themselves are not seen in the stars.  What can be traced in the stars is the rope, that’s tied to their tails, anchored at the extreme southeastern part of the constellation far below and left of the lower left corner of the Great Square.  The right end of Pisces is the asterism, or informal constellation, of the Circlet.  It’s the loop of 5 stars, the rope around the tail of one of the two fish.

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

10/12/2012 – Ephemeris – The constellation of Andromeda and its great galaxy

October 12, 2012 Comments off

Ephemeris for Friday, October 12th.  The sun will rise at 7:54.  It’ll be up for 11 hours and 7 minutes, setting at 7:02.   The moon, 3 days before new, will rise at 5:42 tomorrow morning.

In the east at 9 this evening can be found a large square of stars, the Great Square of Pegasus the flying horse.  The square is standing on one corner.  What look like its hind legs stretching to the left from the left corner star is another constellation, Andromeda the chained maiden.  She is seen in the sky as two diverging curved strings of stars that curve upward.  She was rescued by the hero Perseus, a nearby constellation, riding his steed Pegasus.  Andromeda’s claim to astronomical fame is the large galaxy seen with the unaided eye just above the upper line of stars, the Great Andromeda Galaxy, nearly 2 and a half million light years away.  To the unaided eye the galaxy appears as a small smudge of light.  In binoculars the galaxy is a delicate spindle of light.
