GRB Monitoring System

European groups were among the first involved in the hunts for optical and infrared counterparts of gamma-ray bursts (GRBs). The GRB Monitoring System (GMS) was approved in 1982, and its small Celestron telescopes installed in a small building down the hill from the ESO 3.6-metre telescope. The initiator of the project was Holger Pedersen from ESO.
