Hi,

For some unknown reason, the CONUS and FullDisk images stopped being
recived on our GOES-West ingest systems, so they were not relayed in
the IDD SATELLITE (aka DIFAX for older LDM versions) feed.

From what I can tell, the problem was in the GRB (GoesReBroadcast), not in
our ingest systems. Nonetheless, I restarted the ingest processes on both
of our GOES-West machines at around 2:30 MDT this morning. I watched products
being received, and was puzzled by only seeing the mesoscale sectors. Since
both of our systems were acting the same, and since one is fed from a dish
here in UCAR and the other by a dish at UWisconsin/SSEC, I figured that
the lack of CONUS and FullDisk was upstream of us. This morning I note that
there are CONUS and FullDisk images for GOES-West again, and the volume
plot for DIFAX on freshair1 shows that you should be receiving the images
also.

Please let us know if you are still seeing problems in the feed...
Cheers,
Tom
