Join NASA/JPL for the Last Total Lunar Eclipse Until 2014

The last total lunar eclipse until 2014 will take place the morning of December 10th. That’s tomorrow in case you lost track of the date! For those of us in the Los Angeles area, about half of the eclipse will be visible before sunrise.  

According to the Griffith Park observatory, “you will want a view toward an unobstructed horizon facing west-northwest.” While the eclipse will technically begin at 3:33 a.m. pacific standard time, it will become most dramatic starting “…at 4:45 a.m., when the moon touches the umbra, the well defined, dark, inner shadow of the earth.”
