06/16/2014 – Ephemeris – Dates of the earliest sunrise and latest sunset

June 16, 2014 Comments off

Ephemeris for Monday, June 16th.  Today the sun will be up for 15 hours and 33 minutes, setting at 9:29.   The moon, half way from full to last quarter, will rise at 12:11 tomorrow morning.  Tomorrow the sun will rise at 5:56.

Yesterday saw the earliest sunrise for the year.  My sunrise times will start to show a change on Thursday.  The day-to-day change in sunrise times are now a few seconds.  The summer solstice, or longest day will be this Saturday, and the latest sunset won’t occur until next week Thursday.  The reason these dates don’t coincide has to do with the tilt of the earth’s axis and the earth’s slightly elliptical path around the sun.  Actually the disparity between these dates is more pronounced at the winter solstice when the Earth is closer to the sun and moving faster.  Yup, the sun is farther away now than it was in December.  Actually we’re moving slower now, so summer lasts a few days longer than winter.

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