Bob Moler's Ephemeris Blog

Ephemeris for Tuesday, November 9th.*  The sun will rise at 7:31.  It’ll be up for 9 hours and 50 minutes, setting at 5:21.   The moon, half way from new to first quarter, will set at 8:13 this evening.

High in the south at 9 p.m. can be seen the Great Square of Pegasus.  From the top left star of the square diverge two curved lines of stars that is Andromeda the chained princess.  Just below and left of Andromeda is a slender triangle of stars, none particularly bright.  It has a name you can easily see in the stars, Triangulum, the triangle.  Early Christians saw it as the Mitre of Saint Peter or the Trinity.  Another small constellation seen below Triangulum is the much better known constellation Aries the ram, a small hockey stick constellation, not that hard to spot.  It is the first constellation of the Zodiac, where the sun is supposed to enter on the first day of spring.  Due to the wobble of the earth’s axis, that honor is now given to Pisces.

* Times, as always are for the Traverse City/Interlochen area of Michigan.
