Burhonov \n(UBAI) report on behalf of larger GRB follow-up collaboration:\n\nWe observed the field of Swift GRB 130907A (Page et al., GCN 15183) with \nAZT-22 telescope equipped with SNUCAM of Maidanak observatory starting \nSep., 10  (UT) 11:04:47. We obtained 2 frames with exposures of 300 s in \nR filter. On stacked images we clearly detect the source reported by Lee \net al., (GCN 15192). The astrometry of the source is following\n\nRA(J2000) 14 23 34.01\nDec(J2000) +45 36 36.6\nwith uncertainty of 0.18 arcsec in both coordinates.\n\nThe details of the photometry are following:\n\nt_start, filter Exposure, t-t0,      OT\n(UT)            sec       mid,days\n11:04:47 R      2*300     2.56166    21.44 +/- 0.16\n\nThe photometry is based on a nearby SDSS-DR9 star J142338.63+453547.2 \nwith R mag = 18.181 +/- 0.013 (transformation by Lupton 2005)",
