Details/Specifics of Change:
SNPP VIIRS suffered an uncorrectable error and TMON 37 tripped
causing swap of 1394 Bus from side B to side A. At AOS of SVL
34652, the CrIS 1394 bus also showed a reset and the CDP
root node
will need to be recovered. Engineering team is conducting
recovery for the next 3 orbits between 19:20 - 2300, and will
affect VIIRS and CrIS data. VIIRS instrument will be safed,
reset, and both CrIS and VIIRS will be configured back to
operation.
Affected orbits are:
SVL 34652: 19:20 - 19:31: VIIRS safed and recycled, VIIRS placed
in Op day and producing all data in all bands, including
more data
during night.
SVL 34653: 21:02 - 21:15
SVL 34653: 22:43 - 22:58
Additional orbits may be required.
Some data may not transferred to users because it did not meet
their timeliness requirements.
