report on behalf of the GROND team:


We observed 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). Observations started at 7:03 UT, 
about 21 h after the burst.

The afterglow candidate reported by de Ugarte Postigo et al. (GCN 7719) is 
detected in g'r'i'z'. Preliminary photometry yields g' = 19.95 +/- 0.2, 
calibrated against NOMAD field stars. Observations are ongoing.

We thank Antonio de Ugarte Postigo (ESO) for a rapid communication of the
finding chart.
