Hi all, as expected the propagation conditions at this latitude were
squashed last night by the effects of the last geomagnetic storm. CFH made
one peak (only at 24dBuV) at 0100z here and then dived into the noise for
the rest of the night. Brian's plots show reduced levels on the single hop
path to DCF39 but obviously not as dramatic. Brian's plot also shows about
3dB reduction in the normal daytime levels on Sunday, but with very little
evidence of multipath so I presume this is increased absorption. Mid-day
levels into Europe may improve and be enhanced over the next few days whilst
the after-effects decay away. I would expect the poor night-time levels to
last for about 10 days or so. The "short" sea path to Newfoundland seems to
be able to carry Joe's signals across even under poor conditions.
