Sadly behind a paywall, for us mere mortals. :-(

Is there an excerpt available anywhere?

Cheers.

Hi Dave,

Right, as a fellow mere mortal I sympathize so as part of the moderation
process we work to find accessible copies of papers before or after a
posting goes out to the list.

1988-Fishman-Ionospheric-Disturbances-Gamma-Burst.pdf
1976-Kasturirangan-Ionospheric-Transient-Gamma-Events.pdf
1975-O'Mongain-Baird-Ionospheric-Detection-Bursts.pdf
1973-Brown-Ionospheric-Effects-Cosmic-Ray-Bursts.pdf

Simply append each of the above file names to http://leapsecond.com/pdf/
and you should be all set.

This topic is quite interesting because although it doesn't appear to
perturb GPS reception, it is evident at VLF, so I'm interested to hear
any reports of detection of GRB221009A via WWVB.

For those of you new to the topic, a good summary of the recent "BOAT"
event:
