GCN5162) in Maidanak\nAstronomical Observatory (MAO) with 1.5 m telescope in R and B-passbands on\nMay 26-31, and June 1-2.  Additinnaly we recalibrated observation  with CrAO\nShajn 2.6m telescope (Rumyantsev et al. GCN5181). A photometry is based on\nthe star USNO B1.0 RA=15 31 18.60   DEC=+00 17 35.00   R2=16.35 B2=16.42\nalready used in GCNs (Khamitov  GCN5173, Morgan GCN5175,  Kann GCN5172,\nBaliyan GCN5185).  R-band photometry of the afterglow and upper limits  are\nfollowing:\n\n Mid_time (UT), Telescope,  R_mag\n\n26.7778  MAO1.5 17.98 +/- 0.01\n26.7829  MAO1.5 18.06 +/- 0.01\n26.7883  MAO1.5 18.11 +/- 0.01\n27.7799  CrAO2.6 20.38 +/- 0.07\n27.8143  CrAO2.6 20.47 +/- 0.06\n27.8233  MAO1.5  20.43 +/- 0.04\n28.8014  MAO1.5  21.31 +/- 0.13\n29.8053  MAO1.5  22.06 +/- 0.11\n30.8049  MAO1.5  22.84 +/- 0.24\n31.7938  MAO1.5  23.52 +/- 0.32\n01.8318  MAO1.5  >23.6\n02.8648  MAO1.5  >23.8\n\nThe afterglow is clearly detected in B-filter up to May 29;  B-photometry\nis underway.\n\nThe message may be cited.",
