Hi Laurence, yes you will experience much more interaction with the Geomag
effects on a path like yours crossing the polar region. At a period like
this when there is a proton event, quite a big one, there will be a lot of
PCA (Polar Cap Absorption) as well as all the other nasties that abound in
those regions. Surprisingly enough there was not a lot of auroral activity
which may suggests that although we got a Kp=7 event the shock front only
made a glancing collision with the magnetoshpere.
There is a suggestion that the next expected CME (today sometime) probably
will not be fully Earth facing. This spot certainly has been another big-un
I cant remember many even at the peak that produced so many X-rated
flares....there was another this morning 0800z ish. Joe was very poor
strength here last night. I can just detevct a trace , not decodable, from
him at about 0200z and some traces around 0500 but very weak. I think he
must be about 20dB down on normal.
Cheers de Alan G3NYK

Alan the previous few hours had shown up to 20dB variations of signals of
the Eu path from here on signals near 20Khz - I found this sort of
variability before on TransPolar paths during these disturbed periods on
the
lower LF freqs and certainly not the stable daytime path you'd (I'd)
expect. Period radom fades were in the order of just 30 secs.
