Examples of spectrograph events

The Culgoora Solar Radio Spectrograph observes the radio emmission of the Sun from 18MHz to 1.8GHz. This is required as solar flares can radiate energy over a very broad frequency range. Solar flare radio activity appear as "sweeps" on a solar radio spectrograph display. In particular, there are two types of "sweeps" known as "Type II" and "Type IV", which can indicate that a solar coronal mass ejection has occurred. SWS combines the solar radio "sweep" signature of the event and the solar location and size of the H-Alpha flare activity (obtained from Culgoora Observatory H-Alpha patrol), to determine the geo-effectiveness of the event.

See the document A Brief Introduction of Radiospectrogram Analysis for more information of spectrogram events.
