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.
