Details/Specifics
of change: On January 6, 2020, S-NPP will perform a spacecraft attitude
maneuver for the VIIRS Lunar Calibration, with a roll of -6.45 degrees
centered at 15:16:46Z. 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 be placed in
a contamination safe mode. The timeline of events for this maneuver are
provided below.
The following observatory systems will be affected on January 6, 2020:
14:51:46 Z M-bM-^@M-^S 15:53:46 ZM-B CERES will be inM-BContam-Safe and Standby, science data will not be available
15:06:46 Z M-bM-^@M-^S 15:28:46 ZM-B HRD will be off, data for direct broadcast users will be unavailable
15:11:16 Z M-bM-^@M-^S 15:24:15 ZM-B VIIRS encoder offset and gain will be set for Moon observation
15:11:46 Z M-bM-^@M-^S 15:23:46 ZM-B S-NPP will be pointing off-nadir, collected data may be impacted and not disseminated
