Solar Flare Alert:

An M3.2 flare peaked at 13h10 UT 08 Feb causing a minor R1 radio blackout across the mid-Atlantic.

The flare came from AR3576, which is continuing to be very active.

I've fired up my VLF station signal strength plotter (Spectrum Lab and a long-wire antenna plugged direct to the soundcard input*) and recorded the effect of the flare on some of the signals. The biggest dip can be seen on station GBZ (19.6 kHz) located at Anthorn, Cumbria, approx 500km north of my location. The ionosphere's long recovery is also evident.
