Localization of a type III event on 071231

Thejappa and MacDowall 2010:
have studied the trajectory of the radiating region for this event, probably associated with a C8.3 flare.

Over the 16 MHz to 40 kHz band, assuming the frequencies correspond to the electron plasma frequencies, the radiation corresponds to heliocentric distances from about 1 Rsun to 1 AU.

The illustration shows details of the STEREO WAVES spectra and figures 1 and 14 from the paper.

More to follow on the interesting ray tracing methods used in this study.
