Hi Carol, re: > Ah ok! That makes more sense. Yup :-) re: > How long will it be in mode 4? Here is the last notice we received from ESPCOperations: "Update#1 GOES-16 Mode-4 change did not began until 1820Z Topic: GOES-16 and GOES-17 ABI Mode Change Date/Time Issued: December 04, 2018 1829 UTC Product(s) or Data Impacted: GOES-16 and GOES-17 ABI Data Date/Time of Initial Impact: December 4, 2018 1800 UTC Date/Time of Expected End: December 4, 2018 2200 UTC Length of Event: 4 hours Details/Specifics of Change: On December 4, 2018 at 1800 UTC, the GOES-16 (GOES-EAST) and GOES-17 Advanced Baseline Imagers (ABI) will operate in Continuous Full Disk Mode (mode 4) for 4 hours for testing storage updates. Continuous Full Disk Mode means products will be generated for Full Disk only, every 5 minutes. This test will be cancelled in the event of a Critical Weather Day declaration prior to the event start.

This message was sent to address@hidden" My guess is that they are running both GOES-16 and GOES-17 in mode 4 to test the ground system(s) capability to handle the maximum data rate.
