TITLE: GCN CIRCULAR NUMBER: 38068 SUBJECT: LIGO/Virgo/KAGRA S241102br: OHP/T193 optical observations DATE: 24/11/03 21:49:21 GMT FROM: Christophe Adami at LAM <christophe.adami@lam.fr> C. Adami (LAM), B. Schneider (MIT) report on behalf of a larger collaboration: We observed the field of LIGO/Virgo/KAGRA S241102br and in particular the two possible OTs pointed by Balanutsa et al. (GCN 38057) using the T193cm telescope at Observatoire de Haute-Provence (France) equipped with the MISTRAL spectro-imager. We obtained 3x10 min exposures in the r-band for each of the two MASTER sources (MASTER OT J230458.26+422347.1 and MASTER OT J225647.76+411630.3) from 2024-11-03 19:15 UT to 2024-11-03 20:14 UT. No new sources are detected in these two fields at a limiting magnitude of r > 22.60 AB for MASTER OT J230458.26+422347.1 and r > 22.10 AB for MASTER OT J225647.76+411630.3. The photometric calibration was performed using nearby objects from the PanSTARRS catalog and the magnitudes are not corrected for Galactic extinction. We acknowledge the excellent support from Observatoire de Haute-Provence, in particular Stephane Favard.
