LIGO-Virgo-KAGRA and GEO600 statement on GRB 221009A
Abstract
None of the LIGO, Virgo, or KAGRA detectors were in observing %operation at the time of GRB 221009A. The detectors are currently being prepared for the O4 observing run, which is expected to begin in March %2023. The observing run planning can be viewed here: https://observing.docs.ligo.org/plan/ GEO600 was taking data at the time of GRB 221009A. However, its sensitivity is insufficient to detect any viable GRB progenitor at the estimated z=0.151 (de Ugarte Postigo et al. GCNC 32648), and the data show no evidence of an astrophysical transient at the time of GRB 221009A.
