R. Brivio, M. Ferro, F. Guidolin S. Covino, D. Fugazza (INAF-OAB) report on behalf of the REM team:
We observed the field of GRB 260914A, detected by SVOM/ECLAIRs (Wang et al., GCN 45562) and Fermi/GBM (Hamburg, GCN 45569) 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 J bands, started on 2026-09-15 at 04:25:44 UT (i.e. 0.72 d after the burst) and lasted for about 1 hr.
From preliminary photometry, we do not detect the reported optical/NIR counterpart (Akl et al., GCN 45564; Palmerio et al., GCN 45565; Li et al., GCN 45566; Shi et al., GCN 45567; Saccardi et al., GCN 45568; Saccardi et al., GCN 45579; Yang et al., GCN 45582) down to the following 3sigma limits:
r > 20.2 (AB; calibrated against the Pan-STARRS catalogue),
at a mid-time of 0.76 d after the trigger;
J > 14.2 (Vega; calibrated against the 2MASS catalogue),
at a mid-time of 0.72 d after the trigger.
