GCN: The Gamma-ray Coordinates Network (TAN: Transient Astronomy Network)
Posted 30 Aug 2020:
One of the GCN VOevent servers (209.208.78.170) was, down from ~12:10 to ~12:20UT.
Posted 31 Jul 2020:
The ICECUBE_CASCADE notice type was added to GCN.
Posted 23 Mar 2020 (updated 27 Mar 2020, 04 Apr 2020, 03 May 2020, 08 May 2020; still going 10 Aug 2020):
Due to the policies and constraints during the CoronaVirus pandemic,
my response to your requests and questions may not be as fast as normal.
Example: changes to your site_configuration may take several days
of having to use a remote access connection (all Goddard personnel must tele-work from home).
For "essential personnel" the access time is still 24/7, but the duration is only ~4 hrs/week.
The GCN system distributes:
-
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) made by
ground-based and space-based optical, radio, X-ray, TeV, and other particle observers.
These two functions provide a one-stop shopping network for follow-up sites
and GRB and transient researchers.
The GCN system can be explored using the links above and below.
