The spin maneuver was 4.4% hot, reaching 4.9435 rpm. The calibration used 0.8171. The previous spin down maneuver (6/27/2011) was 2.66% cold with a calibration of 0.8395. The next attitude maneuver is scheduled for Tuesday 05/21/2013. ======================================================================== OCRs: None ======================================================================== Activities: Data Capture: 100% DOY 125-132 2013 ======================================================================== Anomalies: None
