Abstract
The active region McMath 10433 was the source of several flares and radio outbursts during the early part of July 1974. This region was tracked continuously, for several periods during the month at 22.2 GHz using a telescope with a 4 minutes of arc beam. Comparison with the results obtained simultaneously with a normal 7 GHz solar instrument indicate that there is important burst activity occurring at levels below the detection limit of normal solar patrol instruments. The time-development morphology of these bursts is similar to those normally observed and has enabled the simple events to be re-interpreted. A completely new type of event-the fast absorption-has also been recognized. The correlation of the microwave events with SPA events observed on VLF propagation is also discussed.
