Kawai (Tokyo Tech) report:\n\n\"We have observed the Swift/XRT position of GRB 050509B (GCN 3381)\nin V-band with SuprimeCam on the Subaru 8.2m telescope atop Mauna\nKea on the night of May 9.  We obtained 600s exposure images at\n08:08 UT (4.1 hr after the event) and 11:33 UT (7.5 hr after the event),\nrespectively.  We detect the four sources (S1-S4) mentioned in GCN 3401\nalong with other two sources (S5, S6) in GCN 3410.  In addition, another\nsource is detected (S7) within the XRT error circle.  No apparent\nvariability could be observed for these sources during the two epochs.\n\nOur first epoch image is shown at:\nhttp://www.naoj.org/staff/george/Distribute/GRB050509B/GRB050509B.html\"\n\nThis message may be cited.",
