Each temperature transition on September 11 and September 12 will take approximately 15 minutes during the daily housekeeping period prior to the CONUS frame scan at 2102Z. No product impact is expected during these temperature changes. The sounder patch will be changed back to "LOW" setting on October 16, 2017 at 20:45Z. The cooling of detectors will take 1.5-2 hours and there may be some striping during the three or four frames right after housekeeping (21:01-CONUS, 21:24-N. Pacific, 22:01-CONUS, 22:24-Hawaii) 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 Information for Further Information: *ESPC Operations at ESPCOperations@noaa.gov at 301-817-388** ** *Web Site(s) for applicable information: *See http://www.ssd.noaa.gov/PS/SATS/messages.html for this and other satellite related messages.

Date Issued: September 7, 2017 1920Z

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

Date/Time of Initial Impact: September 11 and 12, 2017, at approximately 2045Z

Date/Time of Expected End: September 11 and 12, 2017, at approximately 2100Z,  respectively

Length of Event: N/A

Details/Specifics of Change: On both September 11 and 12, 2017, 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 2045Z (4:45 pm ET).  Each temperature transition on September 11 and September 12 will take approximately 15 minutes during the daily housekeeping period prior to the CONUS frame scan at 2102Z. No product impact is expected during these temperature changes.

The sounder patch will be changed back to "LOW" setting on October 16, 2017 at 20:45Z.  The cooling of detectors will take 1.5-2 hours and there may be some striping during the three or four frames right after housekeeping (21:01-CONUS, 21:24-N. Pacific, 22:01-CONUS, 22:24-Hawaii)
