TITLE: GCN CIRCULAR NUMBER: 33282 SUBJECT: GRB 230205A: OHP/T193 optical observations DATE: 23/02/06 11:57:33 GMT FROM: Damien Turpin at NAOC (CAS) D. Turpin (CEA Paris-Saclay), C. Adami (LAM), E. Le Floc'h, D. Gotz, C. Plasse (CEA Paris-Saclay), B. Schneider (MIT),  S. D. Vergani, A. Saccardi (GEPI, Observatoire de Paris), S. Basa, M. Ferrari, A. Le Van Suu (LAM) report on behalf of a larger collaboration: We observed the field of the possible short GRB 230205A (Ambrosi et al., GCN 33271; Page et al., GCN 33277, Sakamoto et al., GCN 33280) using the T193cm telescope equipped with MISTRAL at Observatoire de Haute-Provence (France). Six exposures were obtained in the R-band (5x20s + 1x60s + 1x120s + 2x180s) under poor weather conditions from 2023 06 Feb. 03:37:06 UT to 2023 06 Feb 04:07:34 UT. In the combined last two frames (mid time ~17.57h after trigger), we do not detect the source and obtain the following upper limit: R > 20.95 mag (AB) The photometric calibration was performed using nearby stars from the PanSTARRS catalog. No further observations using the MISTRAL instrument mounted on the T193-OHP are planned. We acknowledge the excellent support from Observatoire de Haute Provence, in particular Stephane Favard, Jerome Schmitt.
