Each temperature transition will take approximately 15 minutes during the daily housekeeping period prior to the CONUS frame scan at 21:02z. No product impact is expected during and after these temperature changes. The sounder patch will be changed back to "MID" setting on March 21, 2016 at approximately 20:30z just prior to the seasonal Yaw Flip maneuver, and then to "LOW" again on April 11, during eclipse outage at ~8:22z to avoid any product impact. GOES-15 patch management and Yaw Flip is necessary to keep sounder detector temperatures cold and in control while minimizing 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.
