Observations of Solar Bursts of Types II and III at Kilometric Wavelengths from Voyager

Abstract

The Planetary Radio Astronomy receivers aboard the Voyager spacecraft have been recording solar bursts of Types II (Boischot et al. 1930) and III (Riddle 1979) since launch in August and September 1977. The receivers themselves have been described in detail elsewhere (Lang and Peltzer 1977, Warwick et al. 1977). This study restricts itself to data from the 69 channels uniformly spaced between 20.4 and 1326.0 kHz. Each of these channels can be sampled once each six seconds, and the signal to noise ratio on each sample is about 0.8 dB. The sense of circular polarization to which a receiver responds alternates with each sample.
