We took 2x300s exposures in each visit in the broad optical w band.\nWe find a rapidly fading source consistent with the position reported by Eyles-Ferris et al. (GCN 43867) and measure the following preliminary photometry calibrated to the r band:\nEpoch 1: MJD 61098.954 Mag 20.28 ± 0.09\nEpoch 2: MJD 61099.011 Mag 21.08 ± 0.10\n",
