Total eclipses of the moon are unusual, but not rare. Someone on the Earth gets to see one almost every year, but from any given location, you can expect to see a total lunar eclipse about once every 2 1/2 years on average. The last one seen from Colorado was Dec. 21, 2010, so we’ve been in a bit of an eclipse lull.
That’s about to change, big time.The sun, moon and Earth line up perfectly for eclipses only during a brief window of opportunity every six months, our so-called “eclipse seasons.”
Coloradans will be treated to the first total lunar eclipse of the upcoming tetrad. At 11:58 p.m., just two minutes before the stroke of midnight, the full Easter egg moon will begin to slip into the dark umbral shadow of the Earth. Throughout the next hour, the dark “bite” out of the moon will grow in size until, at 1:06 a.m. Tuesday, the moon totally will be immersed in Earth’s shadow.
