The temperature transition will take approximately 15 minutes during the daily housekeeping period prior to the CONUS frame scan at 2102 UTC. _No significant product impact_ is expected during and after this temperature change. This operation will be repeated to raise the patch from "MID" to "HIGH" (88K) at the same time on Sep. 9th, 2016, 20:45z. The sounder patch will be changed back to "MID" setting on September 22, 2016 at approximately 2030z just prior to the seasonal Yaw Flip maneuver, and then to "LOW" again on October 14, 2016 ~2045 UTC. 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. *Contact for Further Information:* ESPC Operations at ESPCOperations@noaa.gov at (301) 817-3880 *Web Site(s) for applicable information:* See http://www.ssd.noaa.gov/PS/SATS/messages.html for this and other satellite related messages.

Topic: GOES-15 (GOES-West) Sounder Patch Temperature Change on Sep 8 and Sep 9, 2016

Date/Time Issued:  September 8, 2016 1312Z

Product(s) or Data Impacted:  GOES-15 (GOES-West) Sounder Data

Date/Time of Initial Impact:  September 8, 2016, at approximately 2045 UTC

Date/Time of Expected End:  September 8, 2016, at approximately 2100 UTC

Length of Outage:  None

Details/Specifics of Change:  On September 8, 2016, SOCC Engineers will change the GOES-15 Sounder patch temperature from its LOW set point (82 K) to its MID set-point (85 K) starting around 2045 UTC (3:45 pm ET).  The temperature transition will take approximately 15 minutes during the daily housekeeping period prior to the CONUS frame scan at 2102 UTC. No significant product impact is expected during and after this temperature change.

This operation will be repeated to raise the patch from "MID" to "HIGH" (88K) at the same time on Sep. 9th, 2016, 20:45z.

The sounder patch will be changed back to "MID" setting on September 22, 2016 at approximately 2030z just prior to the seasonal Yaw Flip maneuver, and then to "LOW" again on October 14, 2016 ~2045 UTC. 

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.
