RadioBurst

Emissions of the sun in radio wavelengthsfrom centimeters to dekameters, under both quiet and disturbed conditions.Radio Bursts can be "Type I" consisting of many short, narrow-band bursts inthe metric range (300 - 50 MHz).; "Type II" consisting of narrow-bandemission that begins in the meter range (300 MHz) and sweeps slowly (tens ofminutes) toward dekameter wavelengths (10 MHz).; "Type III" consisting ofnarrow-band bursts that sweep rapidly (seconds) from decimeter to dekameterwavelengths (500 - 0.5 MHz); and "Type IV" consisting of a smooth continuumof broad-band bursts primarily in the meter range (300 - 30 MHz).
