In preparation for new search and sort features in the GCN Circulars archive, on April 7, 2025 the GCN team will be backfilling the automatically assigned event name (e.g. "eventId": "GRB 250331C") derived from each GCN Circular subject. Event names have been included in all JSON versions of Circulars starting with GCN Circular 37912. The backfill of all prior Circulars will result in the following behavior that may impact some users: - The entire archive of ~40k Circulars will be distributed over Kafka with the new event names. - Revised Circulars will not be redistributed over email.
For more details on this new feature and an archive of GCN news and announcements, see https://gcn.nasa.gov/news.
