03/20/2014 – Ephemeris – Spring is a few hours away

March 20, 2014

Ephemeris for Thursday, March 20th.  The sun will rise at 7:45.  It’ll be up for 12 hours and 9 minutes, setting at 7:54.   The moon, 3 days before last quarter, will rise at 12:24 tomorrow morning.

Just hang on for a few more hours and winter will be over.  At 12:57 p.m. this afternoon (16:57 UT, March 20, 2014) the sun will appear to cross the earth’s celestial equator heading northward signaling the start of spring in the northern hemisphere.  Unfortunately our weather won’t change that instantaneously.  The word equinox means equal night, meaning at day and night are of equal length.  However due to how astronomers actually define the instant of sunrise and sunset we are already above 12 hours daylight, and increasing by 3 minutes a day.  The southern hemisphere of the earth will see the start of autumn as we see spring.  The sun will rise due east today and set due west, which may mean hazardous visibility on east west roads with the low sun for a few days.

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

Addendum

Vernal Equinox
