Kawai (Tokyo Tech) report on\nbehalf of the MITSuME collaboration:\n\n\"We observed the field of GRB 050525 (Band et al.; GCN 3466) with the\n3-color MITSuME 50cm Telescope at Okayama, Japan starting at 12:03(UT)\non May 25, 2005.  We obtained a 5400 sec exposure (120 sec x 45 frames;\nmidtime=13:02 UT) simultaneously in V, R, and I-bands.  We confirmed\nthe optical afterglow (Rykoff et al.; GCN 3465) in R and I bands at\nthe position\n\n\tRA=18:32:32.6, DEC=+26:20:22 (J2000)\n\nwith magnitudes R = 19.30 +/- 0.17 and I = 20.12 +/- 0.29.  We did not\ndetect the optical transient in the V-band image with an upper limit\nof V=19.2.\"",
