*Topic:* S-NPP VIIRS Lunar Roll *Date/Time Issued:* January 14, 2016
18:00:00Z *Product(s) or Data Impacted:* All S-NPP Sensor Data
*Date/Time of Initial Impact:* January 19, 2016 22:29:45Z *Date/Time of
Expected End:* January 19, 2016 23:31:45Z *Length of Outage:* See
Details. *Details/Specifics of Change:*S-NPP will perform a spacecraft
attitude maneuver, for the VIIRS Lunar Calibration, with a roll of
-5.3022 degrees centered at 2016-01-19 at 22:54:45Z. 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, January 19. 22:29:45Z – 23:31:45Z
CERES will
be in Contam-Safe, science data will not be available 22:44:45Z –
23:06:45Z HRD will be off, data for direct broadcast users will be
unavailable 22:49:15Z – 23:02:16Z VIIRS encoder offset and gain
will be
set for Moon observation 22:49:45Z – 23:01:45Z S-NPP will be pointing
off-nadir and collected data during that time period may be impacted
