October 10, the EVE Cruciform Maneuver

Last Wednesday SDO performed an EVE Cruciform maneuver, where the spacecraft points up and down and then side to side. This allows the EVE scientist to track the calibration of the instrument and provide the accurate EUV spectral irradiances they are famous for. But it also causes some of the images from AIA and HMI to be blurred (such as this one in AIA 193).
Next maneuver is tomorrow, October 17, when we do the EVE field-of-view and HMI/AIA flatfield maneuvers.
