LIGO/Virgo/KAGRA Public Alerts
- More details about public alerts are provided in the LIGO/Virgo/KAGRA Alerts User Guide.
- Retractions are marked in red. Retraction means that the candidate was manually vetted and is no longer considered a candidate of interest.
O3 Detection Candidates: 56 (80 Total - 24 Retracted)

0.000000000020943579341 per 1513 years | An additional sky map, LALInference.fits.gz,1 , was uploaded to GraceDB on January 20. However, the preferred sky map is still LALInference.fits.gz,0 , which was uploaded on January 17 and announced in a GCN Notice and GCN Circular 26807. LALInference.fits.gz,1 is from an 'online' parameter estimation run that was started automatically on January 15 and completed on January 20. While the results are basically consistent, it used some data containing low-frequency noise, and thus the LVC parameter estimation team considers the 'offline' PE analysis results LALInference.fits.gz,0 (which was set up to avoid that low-frequency noise) to be more reliable. | 1263097407.75 | S200114f |
