Xue, on behalf of the Beijing Astronomical Observatory GRB \nteam, report:\n\n\"The 58 x 58 arcmin area centered at the BeppoSAX WFC error circle of\nGRB010214 (G. Gandolfi, GCN #933) were imaged on Feb. 14 between 16:48 UT\nto 17:29 UT and 19:02 UT to 21:53 UT (8 to 13 hours after the burst)\nwith the BAO 0.6/0.9-m Schmidt telescope. Image information is as\nfollowes:\n\nNo     Image Name      start time exposure   Filter  Notes\n                          (UT)    (seconds)\n-- -------------------- ---------- --------- ------- --------------\n01 p1751955MG01i039.fit 16:47:45.0  600       BATC-i star elongated\n02 p1751955MG01i040.fit 17:01:25.0  300       BATC-i\n03 p1751955MG01i041.fit 17:09:13.0  300       BATC-i\n04 p1751955MG01i042.fit 17:16:44.0  300       BATC-i\n05 p1751955MG01i043.fit 17:24:00.0  300       BATC-i\n06 p1751955MG01i047.fit 19:02:16.0 1200       BATC-i\n07 p1751955MG01i048.fit 19:24:31.0 1200       BATC-i\n08 p1751955MG01n050.fit 20:24:59.0 1200       BATC-n\n09 p1751955MG01n051.fit 20:47:26.0 1200       BATC-n\n10 p1751955MG01n052.fit 21:10:03.0 1200       BATC-n\n11 p1751955MG01n053.fit 21:32:59.0 1200       BATC-n\n\nThere were no guiding for images (01)-(05) and the first image had very\nbad tracing for the low pointing direction of the telescope. The filters \nused were BATC-i (6660A +/- 240A) and BATC-n (8480A +/- 75A).\n\nVisual comparison of the BeppoSAX WFC error circle area for the combined \nimage of (06) and (07) (detection limit about R=20) and the combined image \nof (08)-(11) with the DSS2 red image shows no afterglow candidate.\n\nThere is a faint object only appeared in image (2) at RA(2000)=17:40:57.68,\nDec(2000)=+48:33:58.3, with R=19.1 (comparison star: RA=17:41:01.76, Dec=\n+48:33:13.7, R=15.6). It was not bad pixel or ghost image. But the \npossibility of cosmic ray could not be excluded completely. Observations\nwith large telescope might be necessary.\n\nThe central part of the image (2) could be found at\nhttp://vega.bac.pku.edu.cn/~zj/grb/grb010214/p1751955MG01i040.gif\n\nThis report may be cited.\"\n\n-- \n========================================================================\nJin Zhu                          | Tel.:  +86-10-62751286 (O)\nBeijing Astronomical Observatory |        +86-314-5520267 (Schmidt dome)\nChinese Academy of Sciences      | Pager: +86-10-96301682333\nP.
