*Topic:* S-NPP VIIRS Lunar Calibration Roll Maneuver Scheduled for
March 18, 2016
***Date/Time Issued:* March 18, 2016 18:00Z
*Product(s) or Data Impacted:* All Suomi-NPP Sensor Data
*Date/Time of Initial Impact:* March 18, 2016 2043Z
*Date/Time of Expected End:* March 18, 2016 2146Z
*Length of Outage:* approximately 1 hour
*Details and Specifics of Change:* On March 18, 2016, Suomi-NPP will
perform a spacecraft attitude maneuver for the VIIRS Lunar Calibration,
with a roll of -2.8601 degrees centered at 21:08:23Z. 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 2016 March 18:
20:43:23 Z – 21:45:23 Z CERES will be in Contam-Safe, science data
will not be available
20:58:23 Z – 21:20:23 Z HRD will be off, data for direct broadcast
users will be unavailable
21:02:23 Z – 21:15:54 Z VIIRS encoder offset and gain will be set for
Moon observation
21:03:23 Z – 21:15:23 Z S-NPP will be pointing off-nadir, collected
data may be impacted and not disseminated
