TITLE: GCN CIRCULAR NUMBER: 41124 SUBJECT: LIGO/Virgo/KAGRA S250720j: Retraction of GW compact binary merger candidate DATE: 25/07/20 03:09:16 GMT FROM: Sourav Das at IUCAA sourav.das@iucaa.in

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

The trigger S250720j is no longer considered to be a candidate of interest. The significance arose from a coincidence with a Fermi GRB trigger. Further analysis by Fermi showed that the event was not a GRB [1].
