Astro Alert: Solstice Lunar Eclipse Tonight

The night of 20 December, or very early into the morning of the 21st depending on your time zone, will feature a total lunar eclipse easily visible in North America, Greenland, and Iceland.  While lunar eclipses are fairly common, this one falls on the same day as the northern winter solstice and that hasn’t happened since 1638!

If you have clear skies, and a warm jacket, be sure to look up tonight around these times:
