    New gravitational-wave candidate, or maybe not? has a 98% probability of being due to noise, so I'm not too sure why it has been sent out Checks are currently underway Rating: 🎧

    Probability of noise 98%, probability of binary neutron star 2%
    Initial sky localization 7000 sq deg
    Initial volume localization. Distance around 230 Mpc

    As month 5 of begins here's our calendar for July - with a total of seven more candidates (that's one almost every four days!) Except for (most likely noise) the others are most probably merging

    Latest candidate is , spotted by and at 14:35:34 UTC. It's very likely to be noise (although if it *is* astronomical then it's most likely a merger). Investigations ongoing. For updates see

    Quota-like propaganda - self-fulfilling prophesy - of 1 event per week suspiciously-correlated to confirmation/publicity of , retracted day of , but publicized upon 96% terr./4% BBH ; declared 97% BBH/3% terr. day of event .

    Retraction count (N=24) and non-rejected event count (N=56) for are far from supportive that your O3 event rate is significant. Only N=4 O3 superevents considered astrophysical, >7 mo. since end of O3. 98% terrestrial event still unretracted:

    The Circular for The false alarm rate is 1.2 per year, which is pretty marginal. The source (if real) would probably be a binary neutron star. Since these are rare, it adds up to a low probability of this being real. Further checks are on-going

    Update on There were some small glitches a few seconds before the merger time. However, these don't seem to affect anything: cutting them out gives similar results. The event remains most probably noise
