An experiment to monitor celestial gamma ray bursts (GRBs) in the energy domain 20 keV-3 MeV was launched onboard the SROSS-C2 satellite on 4 May 1994. The experiment is currently operational in space and has recorded twelve candidate events as on 15 February 1995. Ten of these have been confirmed as genuine gamma ray bursts by their near-simultaneous detection by other GRB experiments in interplanetary space. The scientific objectives of the GRB payload on SROSS-C2, its in-flight performance and preliminary analysis of some of the candidate events are presented and discussed in this paper.
