9th March 2012 Aurora Summary by GM4BYF

Details
Hits: 545

The double CME eruption of March 7th produced a complicated magnetic situation. Most likely both CMEs "ate" each other (hence weakening the strength of the magnetic field BZ). Only the latter part finally produced some aurora, but not as strong as it might have been.

Finally the BZ turned south and around 12:00 UTC the first mid-latitude signals appeared. But the real opening started around 13:00 UTC when signals became strong within a few minutes. Around 16:30 signals dropped and faded away.

On Saturday March 10th another Flare and CME occurred from region 11429, so keep your eyes and ears open for another Aurora on Saturday evening or Sunday. And yet another one due March 12th at 1803 UT (+/- 7 hr).

Comment:

QTF's are influenced by local hill - best direction is often 60 degrees
Tried with GM4CXM on 432MHZ but nothing heard.
