Type III followed by II on 110511; CME on 110509

Two wonderful days for Solar study !!

Culgoora recorded a beautiful type II burst in the 18 to 57 + MHz band. STEREO WAVES A recorded part of it, just below 16 MHz.

A Coronal Mass Ejection powered the type II radiation observed on 110509. The illustration shows details of the CME and the associated C5.2 flare near the East limb.
