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.
