report on behalf of a larger collaboration:

We have observed GRB 080129 (Immler et al. GCN 7226) with the 1.5m OSN 
telescope
at Sierra Nevada Observatory (Granda, Spain). The observations consist 
of a series of
625x19s exposures in I-band, and range from 29.8614 Jan 2008 to 30.0166 
Jan 2008 UT
(0.607-0.762 days after the burst). We do not detect any source in the 
individual frames down
to an average limiting magnitude I < 20.3. However, the combined frame 
does show the
source identified by Bloom et al. (GCN 7229) at I ~ 22.1.
