Tamagawa (RIKEN) report:\n\n\"We have observed the entire region of HETE-2 error circle of\nGRB031026 (N. Butler et al. GCN2429) with 1.0-m telescope Lulin\nobservatory (Institute of Astronomy, National Central University,\nTaiwan) at 26.48-26.72 Oct 2003, corresponding 6-12 hours after the\nburst.  We have imaged 9 fields by CCD camera (10'x10' field of view).\nThese average limiting magnitudes is about 20.9 (SN=3, compared with\nUSNO-A2.0 red magnitudes).  Comparing with Digitized Sky Survey (DSS2)\nimage, there are no new object down to the limiting magnitude.\"\n\nThe observation is summarized as follows:\n ---------------------------------------------------------------------\n  Field  RA          DEC       Start    filter  Exp.(sec) Limit mag.\n                              time(UT)\n   1    03:17:55.5  +28:31:40 11:33       R      300 x 3   21.2\n   2    03:17:56.8  +28:21:41 11:57       R      300 x 3   20.5\n   3    03:17:58.1  +28:11:42 12:23       R      300 x 3   20.0\n   4    03:19:27.2  +28:22:14 12:42       R      300 x 3   20.3\n   5    03:19:26.0  +28:32:13 13:01       R      300 x 3   21.1\n   6    03:19:28.4  +28:12:15 13:20       R      300 x 3   21.2\n   7    03:18:42.0  +28:21:58 17:02       R      300 x 1   21.3\n   8    03:18:40.8  +28:31:57 17:09       R      300 x 1   20.9\n   9    03:18:43.2  +28:11:59 17:18       R      300 x 1   21.5\n ---------------------------------------------------------------------\n\nThis message may be cited.",
