2018 Maneuvers, Past and Future

SDO ran a number of maneuvers during January 2018. Science data may be unavailable or blurry on days when a maneuver is run. During eclipse season the Earth blocks the Sun for up to 72 minutes each day around 0700 UTC (2:00 am ET). This is also midnight Mountain Time, the timezone of the SDO ground station.
  • 01/03/18: RWA Jitter Test Successful: Instruments reported no blurring in images; ISS performance looked reasonable.
  • 01/17/18: EVE Cruciform Successfully Executed
  • 01/24/18: HMI roll, starting at 1500 UTC (10:00 am ET)
  • 02/10/18: Spring 2018 Eclipse Season Begins
  • 02/14/18: Stationkeeping Maneuver #16 (2234 UTC, 5:34 pm ET)
  • 03/05/18: Spring 2018 Eclipse Season Ends
Above is a movie in AIA 171 Å showing the effects of the EVE Cruciform on January 17, 2018. During the HMI Roll the Sun appears to rotate.
