Calibration Maneuvers Today

SDO will execute two calibration maneuvers on April 7, 2021. The EVE Field of View (FOV) maneuver will begin at 1315 UTC (8:15 am ET). The HMI/AIA Flatfield maneuver will begin at 1630 UTC (11:30 am ET). During a calibration manuever the SDO science data may be missing or blurred. HMI science data is only available when SDO is in Sun-pointing mode.

Here is an AIA 171 Å picture from today's maneuver. The straight edges on the left and top show that SDO is pointed slightly away from Sun center. The image is re-centered by the processing software.
