See: http://lf-radio.de/cgi-bin/test/show_wf.cgi?date=17-09-06

May be the strongest flare since 2005 (>x15) ?

I remember the huge flare (>X30) at 2003-11-04 around 20:00 utc:

At that time satellite sensors saturated and the peak strength could be estimated only by phase measurements of VLF signals.
