https://spaceflightnow.com/2018/05/...ather-satellite-has-degraded-vision-at-night/ In short, the 13 channel IR and Near-IR cameras are overheating and not functioning well for about half the day, I believe mostly the nighttime when the imager is pointed towards the sun. Goes17, when(if?) it completes checkout is slated to be the next satellite in the goes-west slot. I hope they get it fixed! The loss of the IR channels at night would be a pretty big blow.
