The unfiltered image was obtained on Apr. 29 between\n(UT) 18:19 and 20:57 (GCN 2190). Based on field photometry (R-band) by\nA.Henden (GCN 2214) we estimate brightness of the OT:\n\nMid.Time     exposure  mag (Unfiltered)\n  (UT)         sec\n\nApr.29.820   39x120    20.20 +/-0.15\n\nThis brightness estimation is consistent with OT decay slope ~ 1 reported by\nJ.Fynbo (GCN 2185).\n\n(We gratefully acknowledge the notion of J.Fynbo regarding the slope decay\nreported in our GCN 2190. Due to typo the slope decay was erroneously\ncalculated as 2)",
