Today's IRU calibration Maneuver has finished. Here is a short movie showing what SDO did. We first pointed the high-gain antennas away from the Earth (that's why we didn't receive any science data). Next came a roll, 2 pitches, 2 yaws, 2 rolls, and a final roll back to our normal orientation. If you have ever waved your smartphone in a figure-8 to calibrate the navigation, you know what we were doing!
