Interesting. Could just be the camera flipping. Their has been some reports of the sun not rising in the right place lately.edit on 22-11-2010 by sabbathcrazy because: (no reason given)

This is just a satellite roll maneuver.
There was one on the 12th of October this year too.
Go to the SDO gallery HERE and input the date and select the AIA 211 (purple) telescope and watch the movie.
On October 12 SDO successfully performed a 7-hour roll maneuver to help calibrate the HMI instrument calibration. The spacecraft roll started at same time as HGA handover operation. This complicated the operational sequences but did not stop either maneuver. While it is easy to point a space-based instrument at the center of the Sun it is more difficult to know the precise location of the Sun's rotation axis. Data from the roll maneuvers help the scientists to understand how their instrument response varies at different angles of the rotation axis. This is then used to more accurately remove the rotation effects from the data.

SDO is a 3-axis stabilized spacecraft, with two solar arrays, and two high-gain antennas. The spacecraft includes three instruments: the Extreme Ultraviolet Variability Experiment (EVE) built in partnership with the University of Colorado at Boulder's Laboratory for Atmospheric and Space Physics (LASP), the Helioseismic and Magnetic Imager (HMI) built in partnership with Stanford University, and the Atmospheric Imaging Assembly (AIA) built in partnership with the Lockheed Martin Solar & Astrophysics Laboratory. Data which is collected by the craft will be made available as soon as possible, after it is received

The sun isn't a solid surface...if it had rotated that much that quickly...don't you think you would be seeing swirling patterns of the flares???
But there is not swirl at all...they all stay exactly the same.
I would guess it was a lens adjustment or something to that affect. I don't think the Sun did a 360.
