GCN: The Gamma-ray Coordinates Network (TAN: Transient Astronomy Network)
This Sunday (26 Apr 15) from 18 to 06 UT (Monday, 27 Apr 15) GCN internet access will be down
for a few intervals while there is a NASA-wide (all Centers) upgrade of the major routers.
There will be a 1-2 hour outage interval near the beginning of the 12-hr total window,
and there will be a few 3-5 minute outages spread across the rest of the total window.
During each of these outages, there will be no socket connections and no email distribution capbilities.
(This was announced to happen last weekend, but it did not.
The GCN system distributes:
These two functions provide a one-stop shopping network for follow-up sites
and GRB and transient researchers.
Locations of GRBs and other Transients (the Notices) detected by spacecraft (most in real-time while the burst is still bursting and
others are that delayed due to telemetry down-link delays).
Reports of follow-up observations (the Circulars and the Reports) made by
ground-based and space-based optical, radio, x-ray, TeV, and other particle observers.
The GCN system can be explored using the links above and below.
