Bruny Island Radio Spectrometer - BIRS

Example of data collected by BIRS

In the data illustrated below, the raw data have been especially processed to remove most of the RFI.

The most common type of solar burst is the fast-drift, type III burst generated by streams of electrons propagating out through the solar corona at nearly the speed of light. These bursts drift from high to low frequencies in less than one minute. Several type III bursts are shown in the next figure.

Slow-drift, type II bursts are generated when shock waves propagate through the corona at  speeds of 500 to 1500 km/sec. An example of a complex Type II burst is shown in the next figure.
