[South Florida DX Association] New M Class Solar Flare

[Bill]

We just had another large M class solar flare explosion at approximately
1727 UTC on February 14, 2011. It produced a sudden ionospheric disturbance
(SID) and attendant radio blackout that has wiped out the shortwave radio
spectrum as high as approximately 10000 khz.

It appears to be an approximate M1.5.
