Pozanenko (IKI) on behalf of\nlarger GRB follow up collaboration report:\n\nWe observed the afterglow of GRB060908  (Evans et al., GCN 5544) with 2m\ntelescope of Terskol Observatory on Sep. 08 (UT) 20:51:45 - 21:14:45. We\ndetect the afterglow on a combined image of 20x60 s exposure. Based on USNO\nA2.0 field stars we estimate brightness of the optical transient:\n\nMid time (UT), Exposure, R_mag\n\nSep. 08.877    20x60 s   20.70 +/- 0.27\n\nIt should be noted that R magnitude of the star  (USNO-B1.0 0903-0022606  R\n= 18.29) used in GCN 5552 (Wiersema et. al) is inconsistent with the\nR-magnitude of the same star USNO A2.0 (0900-00494220   R = 14.9).\nR-magnitudes of other field stars of the two catalogs USNO-B1.0 and USNO\nA2.0 are also inconsistent by ~2.9 mag in average.\n\nThe message may be cited.",
