Re: [ldm-users] GRB data outage.

We definitely saw an outage here for both GOES East and GOES West at UW-Madison 
from like 1620 UTC through just after 17 UTC.

Seems to be up and fine now.

Hi Stonie,

SPC didn't observe any issues with GOES-EAST imagery for the times you 
referenced.  However, the GOES-WEST imagery CONUS/MESO/FULLDISK stopped around 
1621Z and resumed around 1701Z.

The SDM confirms a satellite outage occurred.

The ESPC notices for today don't indicate GOES-WEST will be impacted, only 
GOES-EAST.  Then again, perhaps I missed an email.

ABI Solar Calibration Scans are scheduled for both GOES satellites on July 6.  
See the pasted emails about this below.

The SDM sent the following at 1656Z on the 1st:

NOUS42 KWNO 011656

FYI - we have noticed a GRB outage on G-East and G-West, and could be a

If anyone else has a different experience, please let us know.
