The photometry calibration performed\nagainst the USNO-B1.0 star 1575-0155390 ((J2000) RA = 10:58:34.20, Dec\n= +67:31:45.3), assuming R = 16.7:\n\nT0+      Filter,   Exposure,          OT mag.,  UpperLimit\n(mid, d)              (s)\n\n0.43968 R  51x60                     19.88+/-0.04    21.9\n0.71912 R  25x120+20x180     20.85+/-0.05    22.8\n\nThe power-law decay index during our observation is alpha ~1.8 which\nis consistent with the index reported by Urata et al., GCN 11648.\n\n[GCN OPS NOTE(08aug11): Per author's request, the spelling of the EK\nauthor was corrected.]",
