GCN: The Gamma-ray Coordinates Network (TAN: Transient Astronomy Network)
Posted 23 Mar 2020 (updated 27 Mar 2020, 04 Apr 2020, 03 May 2020, 08 May 2020; 10 Aug 2020, and 18 Oct 20):
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 up to 7 days (instead of the usual 2-4 days).
Being at home teleworking, requires making the site_config file change a remote operation instead of the normal on-site operation.
Which is doable, but I try to keep that method to a minimum. I will wait longer to do the file change
or I will use a weekly 4-hr pass to do work on-site.
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) 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.
