GCN 10253) was observed\nwith the 150 cm telescope of Gunma Astronomical Observatory. Starting\nat 09:09:06 UT on Dec.8 ( 23.1 min after the trigger), both Rc and Ic\nframes were acquired for sets of 5 x 0.5-min and  3 x 2-min exposures.\n\nThe limiting magnitude in combined image is estimated as Rc~20.5 and\nIc~20.0. We did not detect any new point source within the BAT error\ncircle down to the magnitudes of R~20.2 and I~19.5 relative to\nUSNO-B1.0 R2 and I magnitudes, respectively.",
