The observations were started at\n2011-02-05 02:56:38 (UT) and stopped at 2011-02-05 04:24:38 (UT). Four\nunfiltered and four photometric R observations with 300s and 600s exposure\ntimes were made. The afterglow was detected at following position\nRA 10 58 31.16 and DEC +67 31 31.1 consistent those given by Klotz A.\net al.
