Pozanenko \n(IKI) report on behalf of  larger GRB follow-up collaboration:\n\nWe observed optical transient(Guidorzi et al., GCN 15282)  of  the Swift \nGRB 131002A (Barlow et al., GCN 15283)  with 0.4-m SANTEL-400AN \ntelescope of ISON-NM observatory starting on Oct., 2 (UT) 06:55:23 (i.e. \n58 s after burst trigger) in robotic mode. Series of 30 s  exposures \nwere obtained in clear filter.  After PSF subtraction of a nearby bright \nstar we clearly detect the optical transient in each single  frames of \ninitial series. Coordinates of the optical transient are (J2000) 16 52 \n53.29 +82 03 15.6 with uncertainty of 0.25\" in both coordinates. \nPreliminary photometry  is based  on USNO-B1.0 (R2)  stars. The maximum \nbrightness of the OT (15.2  +/-  0.05) was detected in the second frame \nat 0.00141 days after trigger.\n\nLight curve of the initial stage of the OT can be found at\nhttp://grb.rssi.ru/GRB131002A/GRB131002A_ISON-NM_lc.png",
