GCN Circular 7724
A. Rossi (Tautenburg), A. Kupcu-Yoldas, J. Greiner (MPE Garching), S. Klose, R. Filgas (Tautenburg), A. Yoldas, T. Kruehler (MPE), and G. Szokoly (Eoetvoes Univ. Budapest and MPE) report on behalf of the GROND team: We continued observing the field of GRB 080514B (Rapisarda et al., GCN 7715; Giuliani et al., GCN 7716) simultaneously in g'r'i'z'JHK using the multi-channel imager GROND (Greiner et al. 2008, PASP 120, 405) mounted at the 2.2m MPI/ESO telescope on La Silla (Chile). We detect a very slow fading behaviour in the afterglow brightness. The i' band magnitude dropped ~0.05 magnitudes within 1.5 hours, resulting in i'~20.9 around 08:20 UT. This magnitude is ~0.5 magnitudes fainter than the i-band magnitude given by Ugarte et al. (GCN 7719). Please note that the g' magnitude mentioned in GCN 7722 has a typo; it should be g' = 21.2.
