Mirabal (Columbia U.) report\non behalf of the MDM Observatory GRB follow-up team:\n\n\"Using the MDM 1.3m, we obtained 120 minutes of exposure in the K band centered \nat Oct. 31.11 UT, 20 hours after the burst.  All of the 2.1' radius refined \nBeppoSAX error circle (in 't Zand et al., GCN #1123) was covered.  A follow-up \nobservation was performed on Nov. 1.20 UT, with 40 minutes of exposure.  \nConditions were not photometric, and these images have not been calibrated.  \nHowever, no afterglow candidate has been found to an approximate limiting \nmagnitude K > 18.  Additional observations on Nov. 1 covering the position of \nthe radio source VLA J2042+771 reported by Taylor et al. (GCN #1122) reveal no \ndetection to a slightly deeper limiting magnitude.  A prominent galaxy is seen \nat the position of the radio source VLA J2044+7717 (see also Rol et al., GCN #1124).\nIt is constant to better than 0.05 mag.\n\nI-band images were also obtained on both nights using the MDM 2.4m.  Results of\nthese will be reported subsequently.\n\nA K-band image is posted at\nhttp://www.astro.columbia.edu/~jules/grb/011030\n\nThis message may be cited.\"",
