About the GCN A Brief Description There are two parts to the GRB Coordinates Network (GCN): (1) the real-time (& near real-time) distribution of GRB locations detected by various spacecraft (Swift, HETE, INTEGRAL, IPN, etc), and (2) the distribution of follow-up observation reports submitted by the GRB community. Scientific Motivation and General Background Information on GRBs The history and the importance of research into the nature of Gamma-Ray Bursts. Education and Outreach (not done) Gamma-Ray burst research is placed into its scientific context for educators and students. GCN Sites and Links The current observing sites participating in the GCN system are listed. Links are provided when available. INVITATION to Join/Subscribe (Notices, Circulars, Reports) An open invitation for GRB researchers and institutions to join GCN. For "sites" wishing to receive the GCN Notices, the required pieces of information to set up an entry in the "sites.cfg" file are listed. For those individuals wanting to receive/submit GCN Circulars, the requirements are also listed. Who we are The people that built and run the GCN system.
