Some Relationships between Short-Wave Fadeouts, Magnetic Crochets and Solar Flares
Abstract
The purpose of this letter is to report the results of a study of correlations between the three classes of short-wave fadeouts (SWF) and the disk distribution and importance of the associated solar flares. We will also consider relationships between the type of SWF and the occurrence of simultaneous magnetic crochets (sometimes called `solar flare effects' or SFE's). Short-wave fadeouts are reported by the Central Radio Propagation Laboratory of the National Bureau of Standards, Boulder Laboratories, in its monthly tabulations of solar-geophysical data (F series, part B). They are arbitrarily divided into three classes according to the rapidity and general character of the recorded field strength decrease. The three types of fadeouts are illustrated in Figure 1 and described below.
