Solar Dynamics Observatory (automated reports)
Calibration Activities Today 1700-2030 UTC
The SDO Team will power cycle Inertial Reference Unit #2 (IRU-2) today. These cold starts are used to maintain the IRUs and ensure their longevity. The spacecraft will execute a series of off-point maneuvers after the power cycle. These will be done in all three axes, so images will appear to move left to right, nod up and down, and roll to and fro. Once the testing and calibrations are over SDO will return to routine science data collection.
During the calibration activity science data may be missing, blurred, or shifted.
