Melandri (INAF/OAB) report on behalf of the REM team:\n\nWe observed the field of the short GRB 170112A (Mingo et al., GCN 20436) with the 60-cm robotic \ntelescope REM located at the La Silla Observatory (Chile). The observations started at 02:02:55 UT, \n55 seconds after the burst, and were carried out simultaneously in the g, r, i, z and H bands.\n\nA preliminary photometry of the first co-added images indicates that no obvious afterglow candidate \nis detected within the Swift/BAT error circle (Mingo et al. GCN 20436) down to the following 3sigma \nlimiting magnitudes:\n\nr > 18.8 at T-T0 = 763s\nH > 18.0 at T-T0 = 730s\n\n\nMagnitudes are in the AB system and have been calibrated with respect to the 2MASS (H-band) \nand APASS (r-band) catalogues.",
