It's just flashes. The GLM is an optical instrument. Doesn't know what type of lightning. 

I'm not even sure why I typed CGs ( i.e cloud-to-ground). I wasn't even thinking CGs when I made the post. But, yes, just GLM remote sensing data.

Lol yeah. All good. We do some lightning forecast for an energy client in Ontario so I know a little about the differences. Yeah the CG stuff I believe is detected by the land based network. The GLM is better at night because of this. Less interference from the sun.

NOAA2 recon is only about 120-150nm from Sam's eye now, that must make for an interesting and scary ride, there is no land for a very long distance.

Looking at Sam's position and projected track I would hope that there are no yotties leaving the islands for European destinations attm; Sam will be traversing the common sea routes. Sam is bad news even for the largest of ships, let alone the 30-100 foot boats used for the transatlantic crossings.

That's the flight to sample the environment, while NOAA2 will sample the center. Not sure how many passes they will get given the distance from their takeoff location. 

NOAA9 had been haulin' ass at ~515kts at FL40+, just slowed down to 354kt and went up ~3Kft in alt. NOAA2 is just entering Sam's western periphery, much lower and slower.

Hurricane Charlie basically. 

My thoughts exactly.  Probably 942/130 kt.

I'm guessing based on the satellite presentation that the intensity peak occurred a few hours before the recon arrival.
