Three fields of view (14 arcminutes\nsquare) were observed, each of which covered a part of HETE WXM error\nbox (GCN 1468) (http://www.rc.kyushu-u.ac.jp/~yamaoka/GRB020812/FOVouda.gif).\nThe limiting magnitudes are measured by compareing with USNO-A2.0 red\nmagnitudes.  \"Coverage\" shows the percentage of covered area of the\nHETE WXM error box.\n\nFOV\t   1\t\t   2\t\t   3\ncenter\t 20:38:28.8\t20:38:21.0\t20:38:53.3\tR.A.\n(J2000) -05:17:58\t-05:17:24\t-05:23:45\tDec.\nepoch\t 11:08-12:03\t12:05-13:27\t13:34-16:59\tAug. 12 UT + \nexp.\t 38\t\t73\t\t156\t\tminutes\nlim.mag  18.9\t\t20.2\t\t21.2\t\tin R\ncoverage 48%\t\t30%\t\t58%\t\t\nremark\t twilight\n\n  By the comparison with DSS 2 red image, no new source brighter than\nthe limit of DSS 2 is detected.\n\nThis message may be cited.",
