Identification and Characteristics of Source Flares Emitting 3He or Fe Enriched Cosmic Rays in the Period September to December 1977
Abstract
During the observation of solar cosmic rays on the Prognoz 6 and Helios 1 and 2 spacecraft, several events with anomalous composition of accelerated particles (higher abundance of He-3 or Fe nuclei) occurred. Seven such events in the period September to December 1977 were found for which data from the Prognoz 6 solar X-ray photometer are available. This material together with published optical and radio data from terrestrial observatories made it possible to identify more reliably the source flares and describe their characteristics. It turned out that the character of the X-ray emission accompanying the emission of accelerated particles with an anomalous composition shows no pronounced difference from other flares.
