NOAA are experiencing issues with the GEOS satellites, which provide satellite imagery that is used in a wide range of products. NOAA’s updates on their recovery efforts are available here. Basically, GEOS 13 is pointed at the sun and they are trying to turn it around. They are switching to a backup satellite, but that will take a number of hours to complete.
While NOAA is experiencing the outage, satellite imagery in ForeFlight is not available.
