GCN 4966) with 1.5m\ntelescope of Maidanak Astronomical Observatory (MAO) in BRI-bands on April\n18  between  (UT) 19:54 and 22:37 (Hafizov et al. GCN 4990).  A photometry\nof the afterglow is following:\n\nMid_Time(UT), Filter, Exposure, Magnitude\n\n18.857   B   7x180 s     22.38  +/- 0.10\n18.853   R   7x120 s     21.14  +/- 0.05\n18.855   I   9x120 s     20.66  +/- 0.04\n18.934   I   9x120 s     20.35  +/- 0.04\n\nThe photometry is  based on field stars calibration by Henden (GCN 4979) and\nnot corrected for Galaxy extinction. We note our I-observations indicate a\npossible  re-brighntening  of the afterglow.\n\nThis message may be cited.",
