Crochet-Associated Flares.
Abstract
Flares associated with geomagnetic crochets in the interval 1949-1954 were of high average importance but exhibited an atypical distribution on the solar disk, with reduced frequency near the center. The crochet-flares in this interval were not identical with flares associated with "major" sudden ionospheric disturbances There was a close relationship between crochet-flares and flares with wide Ha at maximum Average geomagnetic indices rose to a high maximum on day 2 following crochet-flares with "major early bursts" at radio frequency <200 Mc/s but not after crochet-flares in general.
