There will be an Aqua Drag Make Up Maneuver (DMU) #53 on DOY 300 (10/27/2011). Maneuver start time is set for 300/13:55:00 and maneuver end time is set for 300/14:54:10. The maximum yaw angle for the maneuver will reach 14.35 degrees. The projected loss of pointing accuracy times are 300/13:55:00 - 15:09:10.

MODIS Anomalies:
