The SVOM trigger sb25033102 (GCN Circular 39955) on 2025-03-31T02:04:18 UTC (Tb) is a false trigger, caused by the nearby known bright source SCO X-1, and does not correspond to a real transient.

We apologize for any confusion and inconvenience caused by this mistake.

The Space-based multi-band astronomical Variable Objects Monitor (SVOM) is a China-France joint mission led by the Chinese National Space Administration (CNSA), French Space Agency (CNES), and the Chinese Academy of Sciences (CAS), which is dedicated to observing gamma-ray bursts and other transient phenomena in the energetic universe.
