March 6, 2012 marks the beginning of the SDO Spring Eclipse Season. For the next three weeks the Earth will pass between SDO and Sun at about midnight Boulder time. The length of the occultation will vary from short to almost 72 minutes. Thee eclipses are a normal part of life in a geosynchronous orbit.
The AIA data is currently stale (i.e., delayed) but the problem is being looked at.
