report on behalf of the GROND team:


Our previous report (Filgas et al., GCN 7740) contains a typo in the
reported r'-band magnitude. It must be read r'=21.92 +/- 0.2 instead of 
23.92 +/- 0.2. We apologize for this mistake. 

After a re-analysis of the data, to correct for the effects of the nearby 
star, we conclude that the object is not detected in the g' band to an 
upper limit of g' > 23.0. From the SED of the afterglow, we estimate a 
photometric redshift of z = 3.2 +/- 0.3 using HyperZ (Bolzonella et al. 
2000).
