GCN: The Gamma-ray Coordinates Network (TAN: Transient Astronomy Network)
Posted 07 Jun 2020:
A mistake in the processing code within GCN blocked the distribution of two CALET notices, two MAXI notice and 9 Fermi_GBM_Subthreshold.
This blockage occurred from 00:00 01 Jun to 16:00 07 Jun 2020 UT and was specific to only these 3 notice types.

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 now work from home).
For "essential personell" 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.
