Thanks for sharing Mike! Unfortunate that we're experiencing this and certainly hope that it gets resolved. Having two non-nominal satellites in the same sector is unfortunate but a single band (Band 7/GOES-18) vs multiple bands (Band 10, 12 & 16/GOES-17) is obviously better. Looking forward to further information on what might be happening and potential correction or mitigation.
