Pandey (UPSO, Nainital),\non behalf of a larger collaboration,\n\nreport:\n\n\"We have obtained further imaging of 90% of the error box for GRB\n001105 (Hurley et al. GCN 874), with the 1.23 and 2.2-m telescopes\nat the German-Spanish Calar Alto Observatory and with the 1.0-m\ntelescope at the US Naval Observatory Flagstaff Station, thus\nadding to the results given by Mohan et al. (CGN 875) with the 1.0-m\ntelescope at the U. P. State Observatory. Only the outermost eastern            and western corners of the GRB error box were not covered by our images.\nThe summary of the observations is detailed below:\n\n-----------------------------------------------------------------\n   Date (UT)      Telescope    filter  exposure      limiting\n   (Start)                              (sec)          mag.\n-----------------------------------------------------------------\n  Nov. 06.99       1.0  UPSO     R       300           20.0\n  Nov. 08.45       1.0  NOFS     R       720           20.5\n  Nov. 09.19       1.23 CAHA     R      7 * 500        22.1\n  Nov. 09.22       1.23 CAHA     B       600           21.5\n  Nov. 09.45       1.0  NOFS     I      3 * 600        20.0\n  Nov. 30.23       2.2  CAHA     R      2 * 300        22.0\n-----------------------------------------------------------------\n\nThe photometric calibration was done based on the reference\nstars provided by Henden (GCN 876). A comparison of the different\nimages reveals no fading object down to the limiting magnitudes\ngiven in the table.\"\n\n\nThis message may be cited.",
