Bz was positive all day and into the evening when the skies were clear.
I think it was the arrival of clouds that made it flip. All we can see
now is the streetlight nebula.

Best Regards,
John.

I see it too...........the whole north/eastern sky is green, got lots of
pictures

im near peterborough UK

"Brian O'Halloran" Bz is now strongly negative - and I can spot a strong
glow even though
we're deep in twilight (53N 7W)!

30Km east of London 19 - 20 hrs GMT there is a diffuse glow from NW through
N to NE at upto 30 degrees above horizon. ( Rather reminiscent of looking
north at midnight in June or July ).

Lots of VHF radio and television stations received via auroral mode
propogation.
Nice reception of OH9SIX (50.067Mhz) from the arctic circle in Finland.
Many Swedish, Danish, Lithuanian, British and French and other nationalities
VHF radio coming in.

Good thing I don't rely on the forecast page at
http://www.sec.noaa.gov/pmap/pmapN.html which is giving the latest predicted
update as continuing to show no auroral activity over southern England !

Brian,

Where can you get real time information on the polarity of the IMF Bz?

Thanks
