TITLE: GCN CIRCULAR NUMBER: 45100 SUBJECT: GRB 260706A: REM optical/NIR observations DATE: 26/07/07 12:14:45 GMT FROM: Riccardo Brivio at INAF-OAB <riccardo.brivio@inaf.it> R. Brivio, M. Ferro, P. D'Avanzo, S. Covino, D. Fugazza (INAF-OAB) report on behalf of the REM team: We observed the field of GRB 260706A, detected by SVOM/ECLAIRs (Alaux et al., GCN 45089) and Fermi/GBM (Trigg et al., GCN 45093) with the REM 60 cm robotic telescope located at the ESO observatory of La Silla (Chile). The observations were carried out in the g,r,i,z, and K bands, started on 2026-07-07 at 04:49:10 UT (i.e. 12.6 hr after the burst) and lasted for about 1 hr. From preliminary photometry, we do not detect any uncatalogued source within the EP/FXT error box (Liang et al., GCN 45097) down to the following 3sigma limits: r > 19.4 (AB; calibrated against the SkyMapper catalogue), at a mid-time of 13.5 hr after the trigger; K > 13.6 (Vega; calibrated against the 2MASS catalogue), at a mid-time of 13.3 hr after the trigger.
