Date/Time Issued:Â February

Product(s) or Data
Impacted:Â
GOES-15 (GOES-West) Sounder Data
Date/Time of Initial
Impact:Â
March 4 and 5, 2015, at approximately 2045 UTC
Date/Time of Expected End:Â
March 4 and 5, 2015, at approximately 2100 UTC,
respectively
Length of Outage:Â
N/A
Details/Specifics of
Change:Â Â On
both March 4 and 5, 2015, SOCC Engineers will
change the
GOES-15 Sounder patch temperature from its LOW
set point
(82 K) to its MID set-point (85 K) and then to HIGH
set-point (88 K) starting around 2045 UTC (3:45
pm ET).Â
Each temperature transition on March 4 and March 5 will
take approximately 15 minutes during the daily
housekeeping period prior to the CONUS frame scan at
2102 UTC. No product impact is expected during these
temperature changes.
The sounder patch will be changed back to "LOW" setting
on April 8, 2015 at 8:22 UTC during the sounder eclipse
outage. The cooling of detectors will take 2-2.5 hours
and there may be some striping during the two frames
right after eclipse (10:01 CONUS and 10:24 Hawaii
frames)
GOES-15 patch
management and Yaw Flip is necessary to keep sounder
detector temperatures cold and in control and minimize
fluctuations around each equinox due to the cooler
blanket anomaly discovered right after
launch.
