Lower limit of intensity for the solar activity in microwaves

Abstract

The active region McMath 10433 has produced various flares and bursts in radio frequency in the beginning of july 1974. This region was scanned countinously in 22.2 GHz with a radio telescope showing a 4 min. arc beam, in various periods of the month. In comparison with the results simultaneously obtained with a normal solar radio telescope, in 7 GHz, it was verified that there is an important explosive activity in lower levels in the limit of detection of an usual patrolling instrument. The morphology of these events, in its progress in the time, is similar to that normaly known, and allowed, the re-interpretation of simple events. A completly new type of event was defined: the fast absorptions. The correlation of events in microwaves with 'SPA' recorded in 'VLF' propagation is also discussed.
