These images\nwere obtained from UT 01:03 to 02:25 on 27 December 1998 (15.2 hours after\nthe burst) with the Yale 1m telescope on Cerro Tololo.  The GRB is close\nto the Sun, so the observing time on any night is short even from the\nsouthern hemisphere.  The seeing varied with altitude from 1.3\" to 1.7\"\nFWHM.  \n\nNo variable source was identified in or near the GRB981226 region.\nComparisons were made with the Digital Sky Survey, for which no 'new'\nstars appear.  Also, comparisons were made between the first and last\nimages, separated by roughly 1.2 hours of time.  For the latter\ncomparison, the limiting magnitude for detecting change is close to R=21\nmag.  Further analysis will provide both deeper and more accurate limits.\"",
