4/18/2012 — Please fasten your SDO seatbelts — possible ‘turbulence’ ahead
Regardless of what is causing it — we see the spacecraft camera make a turbulent move to the left right up down and diagonal. Then come back to the original point it started.
I can’t find any description on the SDO site of what is occurring. If you find anything , please put it down below this video in the comment field.

Maneuvers and Images
Thu, 19 Apr 2012
Last Wednesday and yesterday (April 11 and 18, 2012) we performed several spacecraft maneuvers to help calibrate our instruments. On April 4 we did an EVE cruciform and an AIA bakeout. This means the Sun moves back and forth and up and down. AIA images may be noisy (because the CCDs were warmed up to reduce contamination) and the Sun absent during this maneuver. HMI images may not show the Sun, or show it whizzing by as SDO moves.
On April 18 SDO did an EVE field of view and HMI flatfield maneuver.
While we do these maneuvers the data may be unavailable but by doing these maneuvers we keep the instruments healthy.
*Large explosion seen on the Sun’s northeastern limb
April 17, 2012 – SPACE – Magnetic fields on the Sun’s northeastern limb erupted around 17:45 UT on April 16th, producing one of the most visually-spectacular explosions in years. NASA’s Solar Dynamics Observatory (SDO) recorded the blast at extreme ultraviolet wavelengths. The explosion, which registered M1.7 on the Richter scale of solar flares, was not Earth-directed, but it did hurl a CME into space. Analysts at the Goddard Space Weather Lab have analyzed the trajectory of the cloud and found that it will hit NASA’s STEREO-B spacecraft, the Spitzer space telescope, and the rover Curiosity en route to Mars. Planets Venus and Mars could also receive a glancing blow. –Space Weather
