A photometry of the afterglow is following: Mid_Time(UT), Filter, Exposure, Magnitude 18.857 B 7x180 s 22.38 +/- 0.10 18.853 R 7x120 s 21.14 +/- 0.05 18.855 I 9x120 s 20.66 +/- 0.04 18.934 I 9x120 s 20.35 +/- 0.04 The photometry is based on field stars calibration by Henden (GCN 4979) and not corrected for Galaxy extinction. We note our I-observations indicate a possible re-brighntening of the afterglow. This message may be cited.
