Molotov (KIAM), report on behalf of larger GRB follow-up \ncollaboration:\n\nWe observed the field of short GRB 170112A (Mingo  et al., GCN 20436) \nwith AS-32 (0.7m) telescope of Abastumani Observatory  on Jan., 12 (UT) \n15:35:30. We obtained several unfiltered images of the field. Within BAT \nerror circle (Mingo  et al., GCN 2043) we found the source which is \nabsent in USNO-B1.0 at coordinates (J2000) 01:00:49.80  -17:10:17.5 with \nuncertainty of 0.9 arcsec in both coordinates.\nFinding chart can be found at \nhttp://grb.rssi.ru/GRB170112A/GRB170112A_AAO_170112.png\nThe source is  barely visible in DSS2 (R).
