[Bill]

At 0144 UTC on February 15, 2011 the first X class solar flare of solar

cycle 24 occurred. It was an X2.2. It produced a sudden ionospheric
disturbance (SID) and attendant radio blackout that has wiped out the
shortwave radio spectrum as high as approximately 35000 khz on the sun
facing side of the earth.
