EVE Cruciform on April 2, 2014

Yesterday, between 1730 and 2230 UTC (1:30 pm to 6:30 pm ET) SDO did the EVE cruciform maneuver. SDO nods back and forth and up and down. Here is an example of an AIA image taken while SDO was moving, blurred by that motion. These maneuvers allow the EVE science team to maintain the accuracy of their measurements. Accurate measurements allow them to study how much energy is released in late-phase flares and other solar events.
