Hi Laurence yes I can imagine...... the impact was at around 0800z The
bottom of the Dst was around 1500z. NOAA SEC shows the aurora right down to
the Alaskan coast.

Hi Mike it is interesting to see that your "Good Conditions" were just
before a bout of geomagnetic activity :-)) The Dst was nothing special
last night (-40nT) but it plunged to -80nT around noon today. All the
contacts you quote are around the 2000km max range so are one hop and the
precipitated hot electrons did not appear until daylight, but it is
possible these initially aided the Italian copy and your 2000km daylight
paths. These will probably disappear later in the day.
At longer range Roelof reports good signals from Joe VO1NA up to two hours
after ground sunrise. This is a 2-hop path. This could have been due to
precipitared electrons "filling" the morning dip on the 2nd hop but it was
a little early for that. There is also my belief that solar wind
electrons may aid E-layer ionisation so mild activity may lead to better
night-time conditions. My suspicion is that the paths will not be quite so
good tonight....we shall see. The geomagnetic activity does not seem too
intense so will probably soon decay, and we will be back to "normal"
again.

Good conditions and activity last night on the 136kHz band. My Op32
transmission at midnight UTC last night produced reports from nine
countries, including LA, SM, EW6, SV, SP and EA. I also received Op32
from Russia and Italy.
This morning, my transmission at 1035UTC was reported by three
stations around the 2000km mark. IS7SLZ is also readable.
A good time to dust off the LF gear.
