A cable cut in New Mexico is causing some of the SDO telemetry to be delayed to the science teams. As a result, the teams do not know the roll angle of SDO and the images appear to be rotating as we execute the HMI Roll Calibration today between 1500 and 2140 UTC (11:00 am - 5:40 pm ET). The rotation angle will be provided in due course and the science data will have the information to be correctly oriented with solar North up. Once the maneuver is finished the images will again be correctly oriented.
