S130411 -- M6.5 flare in AR 11719 followed by strong radio burst

 S130411 -- M6.5 flare in AR 11719 followed by strong radio burst, with types II and IV radiation, Earth directed CME, Moreton wave

At Learmonth Observatory, Australia:
2700 sfu 245 MHz
3000 sfu 1.415 GHz
100 sfu 15.4 GHz

This flare generated a wonderful type IV display at Nancay, in right and left circular polarizations, strongest in RCP, reaching 20 dB above background, 25 to 65 MHz band. Please see selected Nancay spectra below.

Many thanks to SDO, SOHO, LMSAL, Learmonth Observatory,  e-Callisto Solar Observatories in Ireland and Germany:
