Melandri (INAF-OAR) report on behalf of the REM team:\n\nWe observed the field of GRB 260511A, detected by SVOM/ECLAIRs (Godet et al., GCN 44532) and Fermi/GBM (Fermi GBM Team, GCN 44529) with the REM 60 cm robotic telescope located at the ESO observatory of La Silla (Chile).                 \nThe observations were carried out in the H band, started on 2026-05-11 at 06:15:22 UT (i.e. 110 s after the burst) and lasted for about 10 minutes.\n\nFrom preliminary photometry, we  detect the optical/NIR counterpart (Jiang et al., GCN 44533; Akl et al. GCN 44534; Saccardi et al. GCN 44535; Zheng et al. GCN 44536; Wu et al., GCN 44538, Harper et al., GCN 44545) with the following magnitude:\n\n\nH = 12.9 +/- 0.2 (Vega; calibrated against the 2MASS catalogue),\n at a mid-time of 115 s after the trigger.",
