For Your Information --

HAPPY SUMMER SOLSTICE! The summer solstice will occur early Monday morning (officially, 21 June 2010 at 1128 Z, or 7:28 AM EDT, 6:28 AM CDT, etc.). At that time, the earth's spin axis is oriented such that the sun appears to be the farthest north in the local sky of most earth-bound observers. While most of us consider this event to be the start of astronomical summer, the British call the day the "Midsummer Day", as the apparent sun will begin its southward descent again. For essentially all locations in the northern hemisphere, daylight today will be the longest and the night will be the shortest of the year. Starting Tuesday, the length of darkness will begin to increase as we head toward the winter solstice on 21 December 2010 at 2338 Z. However, because the sun is not as perfect a time-keeper as a clock, the latest sunsets of the year at many mid-latitude locations will continue through about the first week of July -- a consequence of the earth being near aphelion (on 6 July 2010) and the apparent sun moving across the sky well to the north of the celestial equator.
