There are 6 images taken at I-band with exposure time 300 sec(1 frame) and 600 sec(5 frames). Comparison with DSS2 I-band image, a new source was found at RA= 08h 02m 30.1s Dec= -39deg 51' 03.3"(J2000) in our combined image. It is in the error region of the S1 of XMM-Newton observation (M. Santos-Lleo and P. Calderon, GCN2464). There are no new object was observed at S2. Image with comparison DSS2 is posted at : http://cosmic.riken.go.jp/urata/GRB/GRB031203/grb031203_chart.gif Further analysis and observation are in progress." This message may be cited
