06/29/2012 – Ephemeris – Preview July skies

June 29, 2012 Comments off

Ephemeris for Friday, June 29th.  Today the sun will be up for 15 hours and 31 minutes, setting at 9:31.   The moon, 3 days past first quarter, will set at 2:58 tomorrow morning.  Tomorrow the sun will rise at 6:00.

Lets preview July’s skies. The sun, having reached its northern solstice, is beginning to slide southward again, at first imperceptibly, then with greater speed.  The daylight hours will decrease from 15 hours and 29 minutes Sunday to 14 hours 40 minutes at month’s end.  The daylight hours will be slightly shorter south of Interlochen, and slightly longer to the north.  The altitude of the sun at local noon, when the sun is due south will decrease from 68 degrees today to 63 degrees at month’s end.  The sun will be a degree lower in the Straits area.  Despite the warmth, the earth will reach its greatest distance from the sun on Wednesday the 4th.  It’s a time to slow down and appreciate the wonderful stars of summer.

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