Date/Time of Expected End: December 21, 2015 1412Z

Length of Outage: 1 hour

Details/Specifics of Change: Suomi-NPP will perform a spacecraft attitude maneuver, for the VIIRS Lunar Calibration, with a roll of -8.1760 degrees, centered at 2015-12-21T13:35:44 UTC. 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.

The following observatory systems will be affected on 2015 December 21:
13:10:44 UTC - 14:12:44 UTC CERES will be in Cotam-Safe, science date will not be available
13:25:44 UTC - 13:47:44 UTC HRD willbe off, data for direct broadcast users will be unavailable
13:30:14 UTC - 13:43:15 UTC VIIRS encoder offset and gain will be set for Moon observation
13:30:44 UTC - 13:42:44 UTC S-NPP will be pointing off-nadir and collected data during that time period may be impacted
