The Aqua Drag Make Up Manuever (DMU) #49 was completed successfully on DOY 159 (06/08/2011). The loss of pointing accuracy times were 159/13:40:00 - 15:39:10.

There will be an Aqua Drag Make Up Maneuver (DMU) # 50 on DOY 167 (06/16/2011). The maneuver start time is set for 167/14:30:00 and the maneuver end time is set for 167/16:24:10. The maximum yaw angle for this maneuver will reach 14.35 degrees and the preliminary burn duration is 6 seconds. The preliminary loss of pointing accuracy times are 167/14:30:00 - 16:39:10.

MODIS Anomalies:


General Instrument Comments:
