Next week, on October 26, 2016, SDO will perform the EVE Field of View calibration maneuver at 1315 UTC (9:15 am ET) and the HMI/AIA Flatfield calibration maneuver at 1630 UTC (2:30 pm ET).
During calibration maneuvers SDO science data may be unavailable, blurry, or otherwise not usable. On the other hand, the images can be fun to look at! At left is an AIA 304 image showing how SDO is tipped up a little during the first leg of the cruciform.
On October 30, 3016, SDO will experience a Lunar Transit between 1956 and 2056 UTC (3:56 and 4:56 pm ET). The Moon will cover about 59% of the Sun at the peak of this transit.
