Livetweets: April 14-15, 2014 total lunar eclipse

@Patrick_M_Len P-dog, is the lunar eclipse tonight or tomorrow night? News said tonight, but I thought it was tomorrow

@pbuttaa Aw snap, completely slipped my mind, #lunareclipse is tonight (Monday, 4/14)! http://t.co/hUi0IB9wq7 #CuestaAstr210 #mybad

OMG it's starting and it's so beautiful. You guys are really missing out.
