This season's Solstice (Summer in the Northern hemisphere, Winter in the Southern), occurs at 17:16/5:16pm UTC on June 21, 2011. That's 13:16/1:16pm where I am, in the Eastern Time zone, under Daylight Savings Time (UTC-4).
The name is derived from the Latin sol (sun) and sistere (to stand still), because at the solstices, the Sun stands still in declination; that is, its apparent movement north or south comes to a standstill.As the sun stands still, everything else seems to be in motion. Summer is in sway. The succession of insect emergences quickens its pace even as it near its end. Blooms seem to explode, with something new opening each day. Even so, the day after tomorrow will be shorter, the day after shorter still. The arc of gravity's rainbow is masked by this abundance. So we celebrate it, as we should.
