The frequency drift and time splitting of decameter solar radio bursts

Abstract

The frequency drift and time splitting of solar radio bursts are observed with a multi-channel radiometer and a polarimeter at frequencies around 25 MHz. It is found that a majority of noise storm bursts have drift rates between + 1.0 and -1.0 MHz/sec. Two types of unusual bursts with frequency drift are described. The two components of a double burst are found to be polarized to the same degree and in the same sense.
