Today, Jan 27, SDO is performing maneuvers designed to help the EVE team more fully understand its instrument. These spacecraft maneuvers, called cruciforms as they point the spacecraft in a cross-like pattern at multiple steps, happen twice a year. You may notice the Sun stepping across the AIA or EVE/SAM images, or missing altogether today. Don't worry, just another planned calibration activity to help SDO achieve the best possible data!
