C. Clemens, S. Klose (Tautenburg Obs.), J. Greiner, A. Kupcu Yoldas, A.
Yoldas, T. Kruehler and G. Szokoly (Eoetvoes Univ., Budapest and MPE
Garching) (all others MPE Garching) report on behalf of the GROND team:
We observed the field of GRB 080319D for a second time at 23:43 UT on March
23rd, 2008, about 4.3 days after the GRB trigger with 0.5 hrs of total
integration time in g', r', i' and z'.
We do not detect any object within the Swift UVOT error circle (S. Immler et
al., GCN #7458) to the following 3-sigma upper limits:
g' > 24.7, r' > 23.4, i' > 22.7 and z' > 22.5.
This indicates a clear fading of the optical afterglow compared to our first
epoch observations (C. Clemens et al., GCN #7503).
