Guidance System Calibrations Yesterday

Yesterday, June 16, 2021, from 1700-2000 UTC (1-4pm ET), SDO ran calibration maneuvers for the pointing system. These tests were to restart one of the inertial reference units and then a roll of the satellite to help refine some of the parameters in the Kalman filter. During this time science data may be missing or blurry. The tests were successful and will help maintain SDO's pointing accuracy for years to come.

My congratulations to the Flight Operations Team for completing an excellent set of calibration maneuvers!
