Abstract
Low energy celestial gamma ray bursts were discovered1 in 1973 and the detection later confirmed by several groups. In this paper we report the low energy gamma-ray bursts ob served by the plastic scintillator anticoincidence dome of the Small Astronomy Satellite-2 (SAS-2) gamma-ray telescope. Although the high energy gamma-ray telescope of SAS-2 has a threshold of about 20 MeV the large SAS-2 anti coincidence dome (A-dome) which is the outermost element of the instrument provides a very large detector for the high energy portion (⩾0.3 MeV) of these burst events.
