GCN 23686) with the IO:I camera mounted on the 2-m Liverpool Telescope located in La Palma, Spain. Observations started on January 15th at 02:51:47 UT (7.34 hours after the GRB trigger) and we obtained a series of 10x60s images in the H filter.\n\nWe detect the faint optical afterglow (Fernandez-Garcia et al. GCN 23694, Pozanenko et al. GCN 23696, Selsing et al. GCN 23713, Volnova et al., GCN 23722) for which we measure the following magnitude:\n\nH(AB) = 20.35 +- 0.34 mag\n\nThe calibration was performed using four nearby 2MASS stars.",
