Pozanenko (IKI) report on behalf of larger GRB follow-up collaboration:\n\nWe observed the field of the Swift GRB 141109A  (D'Avanzo et al., GCN \n17037) with AS-32 (0.7m) telescope of Abastumani Observatory. \nObservations were performed under mean seeing (FWHM) of 2.4\". We \nobtained several unfiltered images on Nov. 10 starting on (UT) 01:05:04. \n  At the position reported in (Covino, GCN 16932) we marginally \ndetected (S/N =2) the afterglow of GRB 141109A  (Covino, GCN 16932; Xu \net al., GCN 17040; Graham et al., GCN 17041).
