Beginning March 4, 2025 at 12:08:04 UT, data from the INTErnational Gamma-Ray Astrophysics Laboratory (INTEGRAL) will no longer be transmitted to the INTEGRAL Science Data Centre (ISDC), due to the end of scientific operations, more than 22 years after its launch. As a consequence, the INTEGRAL Burst Alert System (IBAS) will be discontinued and GCN Notices will no longer be distributed. The full archive of INTEGRAL GCN Notices is available at https://gcn.gsfc.nasa.gov/integral.html.

The IBAS team thank the scientific community for the continuous support. The GCN team thank INTEGRAL for being an important contributor to GCN over the last 22 years.

The mission pages for GCN Notice producers that are no longer operational have been moved to a submenu for archived missions, including AGILE, BurstCube, and INTEGRAL (https://gcn.nasa.gov/missions/archive).

This news was also reported by the INTEGRAL team in GCN Circular 39563.

For more details on this new feature and an archive of GCN news and announcements, see https://gcn.nasa.gov/news.
