Update #1:  The NOAA POES IJPS team coordinated with EUMETSAT to successfully command the S11 SARP instrument to reset at 1814Z. The USMCC used an in-house technique to generate new time calibration (TCAL) based on the commanding time reported by EUMETSAT. At 1923Z, the USMCC sent the new TCAL to all US LEOLUTs and by 2014Z US LEOLUTs were reporting accurate data for S11.
