Fall Eclipse Season has Begun

Today was the beginning of the Fall 2012 eclipse season. This image in AIA 171 shows that the Earth covered about half of the Sun this morning at 0700 UTC.
With the SDO geosynchronous orbit comes an eclipse season twice each year. They last for several weeks; this will end on September 26 (just in time for our next maneuver).
