06/21/11 – Ephemeris – Summer solstice is today

June 21, 2011

Tuesday, June 21st.  Today the sun will be up for 15 hours and 33 minutes, setting at 9:31.   The moon, 2 days before last quarter, will rise at 12:46 tomorrow morning.  Tomorrow the sun will rise at 5:57.

At 1:16 this afternoon the sun will reach its greatest angle north of the celestial equator or 23 ½ degrees.  The date and the point in the sky where the sun is at that instant is called the summer solstice, or summer sun standstill.  It means the point at which the sun seems poised farthest north before heading southward.  This would be most noticeable if you were monitoring the height of the sun at noon or the sun’s rising or setting point day by day as the ancients did.  Besides being the day with the longest sunlight we, in the northern hemisphere, are also receiving more intense heat from the sun than any other day of the year.  Still hotter weather is in store as the northern hemisphere continues to warm up.

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