tonight is not only the longest night of the year, but also for the first time since 1638 there will be a total lunar eclipse coinciding with the winter solstice! starting at about 1:15 a.m. (e.s.t.) the moon will start to darken as the earth’s shadow moves across it, with the deepest shadow occurring at approximately 3:15 a.m. (e.s.t.), when the moon will take on a reddish orange glow. yeah, it’s the middle of the night, but this won’t occur on the winter solstice again until 2094!
