TITLE: GCN CIRCULAR NUMBER: 39121 SUBJECT: LIGO/Virgo/KAGRA S250202ad: Retraction of GW compact binary merger candidate DATE: 25/02/02 04:44:54 GMT FROM: Souradeep Pal at IISER Kolkata sp19rs015@iiserkol.ac.in

The LIGO Scientific Collaboration, the Virgo Collaboration, and the KAGRA Collaboration report:

The trigger S250202ad is no longer considered to be a candidate of interest. This candidate was initially identified by one or more early-warning analyses by matching partial signal templates to the data. Analysis of additional data up to the putative merger time, with full signal templates, did not make a significant detection, indicating that the initial candidate was likely due to transient noise.
