Monday 1600Z

Alan - transpolar LF signals back to  Europe from here in Alaska continues
to be very poor; DCF39 thru the night has averaged some 30-40dB down rf
wise from the good conditions in the early part of January. The path,
dependant of where the Au Oval is spends a lot of time/distance meandering
in this zone on its way to you. I laugh when I see "no storms/normal"
conditions on some of the prop report pages. If I see a PCA attenuation of
>0.1dB on the IPS web pages I get my skiis out. Given this years weird
weather/stratwarms I might as well get the golf clubs out here in Alaska.
As its near 41F this morning and the snow has gone Im spending more time
sitting in the shack listening to various forms and colors of noise..

I hate protons, especially the energetic types. Its going to be interesting
when we get a 10MeV event, Im wondering if the Au Oval will be pulled so
far south that even though the signal will be hit by greater PCA
attenuation that because of the near right "angle" which signals propagate
across the Au zone that signals may be better? I think I may have seen such
whilst doing research in Northern VE8 back on March 13 1989....or was it 86

The German  77Khz is being similarly hit here, but W/E paths to Japan and
Oz seem less affected.
