  1. Gamma-ray Burst Coordinates Network

    Image GCN.PNG 300px thumb right Diagram of the Gamma ray burst Coordinates Network. NASA GSFC The Gamma ray burst Coordinates Network GCN is a system that distributes information about the location of a Gamma ray burst GRB , called Notices , when a burst is detected by various spacecraft. The GCN also automatically receives and distributes messages, called Circulars , about follow up observations to interested individuals and institutions. Follow up observations may be made by ground based and space based optical, radio, and X ray observatories. GCN has its origins in the BATSE COordinates DIstribution NEtwork BACODINE . The Burst And Transient Source Experiment BATSE was a scientific instrument on the Compton Gamma Ray Observatory CGRO , and BACODINE monitored the BATSE real time telemetry from CGRO. The first function of BACODINE was calculating the right ascension RA and declination dec locations for GRBs that it detected, and distributing those locations to sites around the world in real ... information about the GRB back to the GCN.
