Development of Proton Region with Flare of 7 Sept. 1973
Abstract
The study of the proton flare of September 7, 1973, and the development of the active region proved some earlier known facts. These include the simultaneous occurrence and duration of the rapid phase of expansion of the flare channel, pulsed centimetric radio emission, and the timing of the Y-phase at the beginning of this explosive developmental period. In investigating the time distribution of flare activity and X-ray bursts by means of summation curves, it was again found that several days prior to the occurrence of the proton flare, a marked change in the trend took place. According to white-light coronal photographs from Skylab, the flare generated a huge loop-like structure, which passed through the solar corona, and this phenomenon was responsible for a considerable change in the structure of an appreciable part of the corona above the western limb of the solar disk.
