Szokoly (Eoetvoes Univ., Budapest and MPE \nGarching) (all others MPE Garching) report on behalf of the GROND team:\n\nWe observed the field of GRB 080319D for a second time at 23:43 UT on March \n23rd, 2008, about 4.3 days after the GRB trigger with 0.5 hrs of total \nintegration time in g', r', i' and z'.\n\nWe do not detect any object within the Swift UVOT error circle (S. Immler et \nal., GCN #7458) to the following 3-sigma upper limits:\n\ng' > 24.7, r' > 23.4, i' > 22.7 and z' > 22.5.\n\nThis indicates a clear fading of the optical afterglow compared to our first \nepoch observations (C. Clemens et al., GCN #7503).",
