Jaunsen (U. of Oslo) report: "We ask that the previous message (GCN #545) concerning an optical detection at the position of the Chandra X-ray source is disregarded. As a matter of fact, We do not detect any object at the X-ray position given by Chandra (GCN #544) in our combined 3000s 1.54-m Danish Telescope R-band image (obtained on Feb 11.05 2000 UT) down to a limit of R~23.3. An image of the field is available at: http://www.astro.ku.dk/~brian_j/grb/grb000210 "
