This is the source code for the General Coordinates Network web site, https://gcn.nasa.gov. The General Coordinates Network (GCN) is a public collaboration platform run by NASA for the astronomy research community to share alerts and rapid communications about high-energy, multimessenger, and transient phenomena.

GCN distributes alerts between space- and ground-based observatories, physics experiments, and thousands of astronomers around the world.

For more information, see What is GCN? or check out our slide deck.
