Veilleux\n(UMD) report on behalf of a larger collaboration:\n\nWe observed the field of the variable source reported by Marshall and Cenko\n(GCN 17139) with the Large Monolithic Imager (LMI) on the 4.3m Discovery\nChannel Telescope (DCT) at Happy Jack, AZ from 2014/12/07 11:01 until\n2014/12/07 11:08 UTC (starting 119.74 hours after the observations reported\nby Golenetskii et al. in GCN 17131). A source is clearly detected at the\nlocation of the source identified by UVOT in u', g', r', i' and z'. Using\nnearby point sources from SDSS for calibration we measure r' = 20.57 +/-\n0.03. The coincident SDSS R10 source has r' = 22.65 +/- 0.20, confirming\nthat the source is indeed transient. At 0.8 arcsecond seeing, the source is\nunresolved.\n\nThis magnitude is reported in AB magnitude and is not corrected for\nGalactic extinction in the direction of the source.\n\nFurther observations are planned to investigate possible variability of\nthis source.\n\nWe thank the staff of the Discovery Channel Telescope for assistance with\nthese observations.",
