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

The trigger S240624cd is no longer considered to be a candidate of interest. The power in the strain channel was also witnessed in environmental monitors pointing to a data quality problem with the Livingston detector. The candidate found was not coherent between the Livingston and the Hanford detectors, and was not confirmed by similar burst pipeline analyses.
