Instrument Calibrations on Wednesday

The shaking of the images on Wednesday was due to two image calibration maneuvers. The EVE Field of View started at 1315 UTC and after that ended the HMI/AIA flatfield started at 1630 UT. SDO returned to normal data operations at 1900 UTC. These maneuvers allow the scientists to calibrate their instruments and keep the data flowing.
