Pozanenko (IKI)  report on behalf \nof  larger GRB follow-up collaboration:\n\nThe 0.45-m telescope of  ISON-NM observatory robotically followed up the \nfield of the Swift GRB 120308A  (Baumgartner  et al.,  GCN 13017 )  on March \n8, 06:16:55, i.e. 3.3 minutes after burst trigger. In the first frame of 30 \ns exposure we do not detect the optical afterglow (Virgili et al.,  GCN \n13018 ) up to R~16m.  However in a stacked several first images of 1800 s \nexposure we clearly detect new source in coordinates 14 36 19.95 +79 41 12.3 \nwhich are coincide with coordinates of the optical afterglow (Virgili et \nal.,  GCN 13018 ). The magnitude of the source at (UT) 06:38:10 (middle \ntime) is  R~17.30m. All images are unfiltered and calibrated against \nUSNO-B1.0 R2 field stars.\n\nAll results are preliminary. Observation is continuing.",
