SUBJECT: LIGO/Virgo/KAGRA S231030av: Retraction of GW compact binary merger candidate

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

The trigger S231030av is no longer considered to be a candidate of interest. This candidate was initially identified by an early-warning analysis 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.
