Date/Time of Expected End: Until Next Month's Coefficient Update 

Length of Event: TBD

Details/Specifics of Change:  On 12 November 2024 at approximately 12:00 UTC, the following update of the calibration coefficients was implemented in the level 1B processing for NOAA-18, NOAA-19, MetOp-B/1, and MetOp-C/3 for the month of November. These coefficients are intended to be optimal on November 26, in the middle of the two scheduled updates.
