Radio Emission:

Emissions of the sun in radio wavelengths from centimeters to dekameters, under both quiet and disturbed conditions. Type i. A noise storm composed of many short, narrow-band bursts in the metric range (300 - 50 mhz). Type ii. Narrow-band emission that begins in the meter range (300 mhz) and sweeps slowly (tens of minutes) toward deka- meter wavelengths (10 mhz). Type ii emissions occur in loose association with major flares and are indicative of a shock wave moving through the solar atmosphere. Type iii. Narrow-band bursts that sweep rapidly (seconds) from decimeter to dekameter wavelengths (500 - 0.5 mhz). They often occur in groups and are an occasional feature of complex solar active regions. Type iv. A smooth continuum of broad-band bursts primarily in the meter range (300 - 30 mhz). These bursts are associated with some major flare events beginning 10 to 20 minutes after the flare maximum, and can last for hours. A smooth continuum of broad-band bursts primarily in the meter range (300 - 30 mhz). These bursts are associated with some major flare events beginning 10 to 20 minutes after the flare maximum, and can last for hours.
