June 21 at 11:39 a.m. marked the 2015 Summer Solstice. This is when the sun reaches its furthest point north of the equator. For those in the northern hemisphere, it means that June 21 is the longest day of the year. On the solstice, the sun rose at 6:20 a.m. and set at 8:23 p.m. at the Insperity Observatory. The daylight lasted 14 hours, 3 minutes and 32 seconds. Sadly, it also means that we are beginning the 6-month journey to the shortest day of the year, the Winter Solstice. Enjoy the warmth, and the long days while they last. By June 22, the day was already one second shorter.
Come join us at the next Public Night at Insperity Observatory (humbleisd.net/observatory) and check out our Analemma and its Gnomon. They show where the sun is in the sky throughout the year. Public Nights are the first Friday, monthly.
