Using ISAAC on UT1 we have obtained Js and Ks\nobservations and with FORS2 on UT2 we have obtained V, R and I\nobservations. Our observations were carried out on April 29.94 and \nApril 30.20 UT, i.e. 12.6 and 18.1 hours after the burst. We confirm \nthe fading of the afterglow candidate proposed by Gilmore et al. \n(GCN 2184). Between our two epochs the source has faded by 0.43 \nmagnitudes in the V band. In our second epoch image the magnitudes of \nthe source are about R=22 and Ks=17.9 implying a decay slope close to\n1. The source is located 1.2 arcsec from an extended source NW of \nthe afterglow position. This source has magnitudes of about R=24\nand Ks=18.2. Our absolute photometry is based on preliminary zeropoints \nand is hence subject to considerable uncertainties. \n\nWe note that the source is located 1.2 arcmin from the center of and\nis hence formally outside the 90% SXC error-circle.\n\nWe acknowledge excellent support from the Paranal staff, in \nparticular Cedric Ledoux, Rachel Johnson, Poshak Gandhi and Elena\nMason.\"",
