21   The winter solstice occurs at 2338 UT as the sun reaches its farthest point south. Today marks the shortest day and longest night of the year. This morning, a total lunar eclipse is visible across North America and most of the eastern Pacific, including Hawaii. The eclipse begins at 0632 UT when the umbra first touches the moon. Totality begins at 0740 UT and lasts until 0854 UT. The last bit of shadow leaves the moon at 1002 UT. Unlike solar eclipses, lunar eclipses are completely safe to watch. Full Cold moon at 0813 UT
