Alan,

Hartmut's copy is along the same lines...weak copy of Jay early, and 
then very little after that. I note that there was an area of 
thunderstorm activity in the central Mediterranean area, but that's 
quite a distance away.

I like your multiple ring theory. It did seem that signals recovered 
very quickly from the Kp=8 event. It would be nice to have some other 
data that supports the concept.

For those that follow the http://www.spaceweather.com site: Some of the 
main page data is not being properly refreshed, and is a couple of days 
out of date. The underlying graphs are correct, though.

One correction from last night: XES did not go on the air until 0405. I 
was a bit sleepy when I made out the log entry. It should be on by 0300 
tonight.
