Pagnini (Notre Dame) report:\n\nWe observed field of GRB 101204A beginning on Dec. 6.51 (UT) with\nthe Vatican Advanced Technology Telescope (VATT) and VATT4K CCD\ncamera. The imaging was centered on the original BAT position\n(Cummings, GCN 11440) and were obtained 1.52 days after the burst.\nSix R-band images were taken in poor conditions. The optical\nafterglow candidate identified by Swift-UVOT (Sbarufatti et al., GCN\n11442) is detected in the VATT images.\n\nThe deepest images centered on Dec. 6.521 give R=20.0+/-0.1 mag calibrated\nfrom the USNO B1.0 star at 11:10:13.908 -20:26:07.8 with R2=17.74 mag.\nThe observations span less than 20 minutes so it is not possible to\ndetermine if the source is fading.",
