SOFT SOLAR X-RAY BURST CHARACTERISTICS.

Abstract

Solar x rays in the wavelength range 2 - 12A (1 - 6 keV) have been monitored by detectors on the satellites Explorer 33 (since July 1966) and Explorer 35 (since July 1967). These x-ray data have been converted into absolute flux values by computer for the above data. In this large quantity of data, thousands of x-ray bursts are observed. A means was devised to examine the burst component of the flux by computer. A total of 4028 bursts have been identified in this manner for the period July 1966 to September 1968. This burst sample was examined for possible parameters by which to classify bursts. In a comparison with other flare data, the relationship between H alpha flare occurrence and x-ray burst occurrence was examined. The distribution of soft x-ray bursts with heliographic longitude was determined in order to test the non-thermal, directional emission proposal. A comparison was made with harder (photon energy greater than 6 keV) solar x-ray bursts to study the temporal and amplitude relationship of the two phenomena.
