Observations from the gamma-ray burst experiment onboard the SROSS-C satellite.
Abstract
A gamma-ray burst (GRB) experiment was launched onboard the SROSS-C satellite on May 20, 1992. The experiment covered an energy domain of 20keV-3MeV and had a time resolution of 2 ms. It operated satisfactorily till the re-entry of the satellite on July 14, 1992. The experiment recorded high resolution temporal and spectral data on a few interesting events. Details of three of them and their preliminary analysis are presented. Of these three events the one which was detected on June 29, in particular, exhibits strong oscillations with a pronounced periodicity of 237.03 +/- 0.5 ms. Possible explanations for this fast variability are explored in this paper.
