Variations in the Profiles of the Gradual Rise and Fall Bursts for June 11-15 and a High Resolution Study for the Major Event of June 15, 1972
Abstract
Solar flux observations were made with operations on 2800 and 2700 MHz to include examples of the Gradual Rise and Fall (GRF) bursts. The June 11 to 15, 1972 records showed a variety of long enduring, low intensity Simple 3 bursts. The major GRF event of June 15th attained a peak flux of 57 units before decline. During the burst decline, high resolution drift curves were taken and the relationships were compared to known observations. Hydrogen-alpha spectroheliograms on the 14th showed the existence of a dark filament in the region occupied by plage elements. The disappearance of the dark filament on the 15th was related to the brightening of these elements.
