Hi Alan
 
Well   everything  is  going  South  in more  ways  than one  ,  2  nights  ago  I was  decoding  with   10 watts  with  Halldor ,  to  night ,   not  a  beep ,
pa3abk  also  only  showing  south  .. not  ideal  ,  but  there  are  monitors    mid  uk ,   south coast  and  France ,  so  if the  Icelandic  path is  blocked ,  the  close in  stations  should   see  something ,  Top  Band is  now  also  showing  in Iceland ,  A middle  UK Top band  Rx  station  would  complete the  Opera  input to  the  event ..

Hi Graham this is going to be "interesting" to say the least. The Dst has plunged to -225nT and looks in freefall  NOAA has just issued another Kp=8 alert. This really is filling up the ring current, the effects may well last two or three weeks! BUT daytime levels may be enhanced tomorrow maybe Friday too if there is any more activity.  The interesting thing is that these hot precipated electrons will not decay like the normal daytime photo-dissociated variety. So whilst the status may not be what we expected, there is a chance to see if we can detect a decay rate for the hot electrons during the eclipse. It will be a much more complex situation, but it may be necessary for some reasonably powerful stations to be active, because the eclise may cause propagation to collapse rather than improve.
 
This becomes an even rarer event in terms of LF propagation.!!

QSP ....  Weather  report  from  Iceland  
 
 
A geomagnetic storm since early this morning is
playing havoc up here in the Aurora zone.
Total blackout on lower bands, only occasional
raspy sig hrd on the higher. Let's just hope it
passes in time for Friday!
