behalf of the GROND team:

GROND (Greiner et al. 2008, PASP 120, 405), mounted at the 2.2m ESO/MPI 
telescope at La Silla Observatory (Chile), started observations of the 
field of GRB 080805 (Pagani et al. 2008, GCN #8059) in g'r'i'z'JHK at 
07:45 UT, 3.5 min after the burst. We detect an optical/NIR afterglow 
candidate in the XRT error circle (Pagani et al. 2008, GCN #8059) in 
griz at:

RA(J2000): 20h 56m 53.44
DEC(J2000): -62d 26' 39.8"

with uncertainties of 0.5".

We measure the following magnitudes, calibrated against USNO-B1 field stars:

g = 21.7 +- 0.2
r = 20.5 +- 0.1
i = 20.1 +- 0.1
z = 19.9 +- 0.1

No statement about fading can be made at the moment. If this is the
afterglow of GRB 080805, then its redshift is smaller than 3.5.
