Gezari (UMD) report on behalf of a\nlarger collaboration:\n\nWe observed the field of GRB140606B/iPTF14bfu (Singer et al., GCN 16360,\nFermi 432717114, Burns et al. GCN 16363) with the Large Monolithic Imager\n(LMI) on the 4.3m Discovery Channel Telescope (DCT) at Happy Jack, AZ from\n2014/06/08 9:05 to 2014/06/08 09:41 UTC (starting 29.9 hours after the\nFermi trigger).  A source is clearly detected at the location of the\noptical afterglow in g', r', i', and z'.  Using nearby point sources from\nAPASS for calibration we obtain the following detections:\n\ng' = 22.8 +/- 0.04\nr' = 22.2 +/- 0.04\ni' = 22.1 +/- 0.05\nz' = 22.1 +/- 0.08\n\nThese magnitudes are reported in the AB system and are not corrected for\nGalactic extinction in the direction of the GRB.  Further observations are\nplanned.\n\nWe thank the staff of the Discovery Channel Telescope for assistance with\nthese observations.",
