Selenelion

lunar-eclipse-blood-moon

We are going to have a lunar eclipse on Wednesday morning.  It will be the second “blood moon” of the year, and it will be a selenelion – an extremely rare event in which both the sun and eclipsed moon are actually visible at the same time.

Selenelions were once said to be impossible.  Lunar eclipses are rare enough, but having both the sun and moon visible increases the odds exponentially. That can only occur for a few minutes at sunrise or sunset.  This one will be at sunrise. 

I don’t know if it will be visible here at the Boggy Thicket.  After several days of crystal clear skies, the clouds are rolling in this morning, and almost every celestial event in the past year – meteor shower, lunar eclipse, even the passing of the International Space Station – has been obscured by cloud cover.  At least I won’t have to get up at two a.m. just to be disappointed.
