Storm delayed

Well, although geomagnetic conditions were pretty unstable yesterday (peak Kp~4), the expected CME didn't seem to arrive on schedule.  At the moment, NOAA are now expecting, with "diminishing confidence" a storm today, peaking at G3 levels.  I suspect it may never occur.

Even so, the conditions were sufficiently rough to totally obliterate any DX overnight.  The only stations I heard at all at 14MHz WSPR were 5W from G0CCL - an unusual duplicate spot event occurring only once at 01:06UT, and a single reception of 0.2W from DK9ES at 01:26UT, both stations around the -24dB level.  This was, respectively, 26 minutes and 6 minutes before a magnetic field shock was detected at the L1 point at 01:32UT.

The recent, quieter-conditions, near-continuous overnight reception of stations from 8P, 9Z and CE simply vanished at 20:06UT.

My own 1W transmissions were only heard once, at 00:44UT, by 0E9GHV, at -21dB, during a temporary rebound to quieter conditions.
