The Edge of Night
October 30, 2000
This full disk image of our planet was taken from the Meteosat satellite on Friday October 27, 2000, at 6:00 p.m. Greenwich Mean Time (GMT), which is 2:00 p.m. Eastern Daylight Time. The terminator, the boundary between daylight and nightfall, is seen slanting across the Earth - night is moving from east to west (right to left). North America is near the upper left rim of the disk. Most all of Europe and Africa are now in darkness, and it's dusk over the central Atlantic. Much of the Atlantic Ocean is cloud covered, as is most of Antarctica, at the bottom of the image. Note that Antarctica is still receiving sunlight. Since it's spring in the Southern Hemisphere, the high southerly latitudes now only experience darkness a few hours each day. In the US, daylight savings time has now ended (we're now on standard time), and darkness is arriving an hour earlier than it did on Friday - the edge of night will be upon us earlier and earlier for the next six weeks or so.
