Hi all, and congratulations to Laurie^2.

A quick look at Steve's (W3EEE) plot for last night does show a good peak
between 0450 and 0600z.This is a little surprising as I would not have
expected the path to Steve to be a very good predictor of Trans-Arctic
propagation. I think Laurie has just crept in, in an aurorally quiet period
(?), but the fact that absolutely top conditions were not necessary is very
encouraging. Conditions have recently started to slowly recover from the
geomagnetic activity we suffered in late January. The Kp index is still
"unsettled" and there are predictions of increased solar wind and possible
CME from a geoeffective coronal hole, so this "window" may not last too
long"
The Trans-Arctic path may be very complex and reception may depend on being
able to "skip" a signal under the auroral belt, which will provide severe
absorption. For this reason it may not always be good when other paths are
good and it may also be very dependent on the relative position of the
transmitting and receiving stations. There are also several other effects
that can have a bearing on Trans-Arctic propagation. These are well
described on Tom's KN4LF web site.

Well done both,
Cheers de Alan G3NYK
