Lou(THCA) on behalf of the East Asian collaboration\nreport:\n\n We observed the SWIFT/BAT error region for GRB 050309 (trigger\nno. 107873) using Lulin 1-m telescope at Taiwan. We imaged a single\nR-band 300 sec exposure at 11.14 UT (~ 25 mins after the burst\n). Compare with DSS-II image, no new object was found. The limiting\nmagnitude is about 19 mag ( S/N=3 , with USNOB1.0 catalogue).\n\n\nThis message may be cited.",
