Tamagawa\n   on behalf of the KISO GRB Team:\n\n We have observed the field of GRB020317 (= H1959 ) with the KISO\nobservatory 1.05m schmidt telescope at 2002 March 18. All images\n(R-band) were taken with the 2kx2k CCD camera ( 50' x 50' field of\nview). These images cover with the whole HETE-2 error circle reported\nin GCN Notice (HETE Ground Analysis seq_num: 5).\n\nOur data;\nDate  Time (UT)     Exposure   Limiting mag.(R, SN=3)  seeing size\n03-18 12:43 - 12:58 300sec x 3 20.8  5.0\"\n03-18 17:19 - 17:55 300sec x 6 18.1  7.5\" (Bad weather condition)\n\n# Limiting magnitude was estimated by comparison with\n# U0975_06481732(10:23:25,+12:42:05,R(USNO)=16.1).\n\n We detected six point sources which are not in DSS-2 image. Two\nsources were identified with minor planets using Minor Planet Checker\n: http://scully.harvard.edu/~cgi/CheckMP. Four souces are not\nidentified. Because of the bad weather condition, we cannot find\ntheir time variability.\n\nCoordinates of these sources are:\n\n   RA(J2000) DEC(J2000) mag.(R)\n1  10:24:25  +12:51:55  18.0   <= minorr planet\n2  10:24:09  +12:48:33  17.3   <= minorr planet\n3  10:23:10  +12:33:17  19.6\n4  10:22:40  +12:32:02  18.5\n5  10:22:39  +12:44:02  19.0\n6  10:22:20  +12:36:55  19.1\n\nAstrometric uncertainties are 1 aresec, and photmetric uncertainties\nare 0.1 mag. for 19 mag. objects.\n\nThis message may be cited.\n\n[GCN OPS NOTE:  This message was received 8 hours ago, but due to my mistake\nin the list, it as delayed.]",
