GCN 3525) by using 1.0-m telescope at Lulin Observatory, Taiwan. The R band observations started at 16.14 UT ( about 6.95 hours after the burst). No source was detected at the X-ray afterglow position ( Pagani et al. GCN 3528). The limiting magnitude of our R band co-added image ( 300sec x 8) is 21.1 by comparing with USNOB1.0 stars.
