*Topic:* S-NPP VIIRS Lunar Calibration Roll Maneuver Scheduled
for April
17, 2016
*Date/Time Issued: *April 17, 2016 1545Z
*Product(s) or Data Impacted:* All Suomi-NPP Sensor Data
*Date/Time of Initial Impact:* April 17, 2016 1118Z
*Date/Time of Expected End:* April 17, 2016 1220Z
*Length of Outage: * See Details
*Details and Specifics of Change: *On April 17, 2016, Suomi-NPP will
perform a spacecraft attitude maneuver for the VIIRS Lunar Calibration,
with a roll of -3.6343 degrees centered at 11:43:12Z. 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 April 17, 2016:
11:18:12 Z – 12:20:12 Z CERES will be in Contam-Safe, science data will
not be available
11:33:12 Z – 11:55:12 Z HRD will be off, data for direct broadcast
users
will be unavailable
11:37:41 Z – 11:50:43 Z VIIRS encoder offset and gain will be set for
Moon observation
11:38:12 Z – 11:50:12 Z S-NPP will be pointing off-nadir, collected
data
may be impacted and not disseminated
