Hello everyone,

It has been over a week (possibly more due to lack of weather) where we are not 
seeing any GLM level 3 products. We ARE seeing lightning strike data
just fine (level 2 data):

OR_GLM-L2-LCFA_G19_s20253242246000_e20253242246200_c20253242246218.nc

However, we are NOT seeing:

GOES GLM Total Optical Energy
GOES GLM Minimum Flash Area
GOES GLM Flash Extent Density

A notifyme shows no level 3 products being received on idd or iddb:

localserver % notifyme -v -h idd.unidata.ucar.edu -p GLMISatSS/Level3 -o 3600 -O

Is anyone seeing this missing data?

Thank you for any help!
