"Effective immediately, the GBM team will begin issuing GCN circulars for triggered gamma-ray bursts. These will include human-in-the-loop localizations and, for bright GRBs, spectral results. Burst triggers occur approximately once per day. The latency will be up to 1 or 2 days initially, dropping to a few hours over the next 3-4 weeks. We expect to begin sending automatically generated notices...Full Text
