Details/Specifics of Change: Suomi-NPP will perform a spacecraft attitude maneuver, for the VIIRS Lunar Calibration, with a roll of -7.1705 degrees centered at 2015-11-22 T0 4:20:25Z. Science data may be impacted while the spacecraft is pointing off-nadir during the attitude maneuver and the CERES instrument will not provide nominal science data as it will placed in a contamination safe mode. The timeline of events for this maneuver are provided below.
