R-band images (4 x 180 s exposures)\nwere taken between (UT) 21:28 and 21:42 March 5, i.e. 46 minutes after\ntrigger and before ground analysis retraction of the trigger 107518 as GRB.\nIn comparison with DSS2 (red plate) no new source down to R~20 was found in\na stacked image within  error box. The limiting magnitude of the stacked\nimage is R~22.0.\n\nThis message may be cited.",
