The 60cm robotic telescope BOOTES-IR located at Observatorio
Sierra Nevada, Southern Spain, observed automatically the
position of GRB060204C (Grupe et al.  GCN 4663). The telescope
slewed automatically within 3m5s after recieving the GCN alert
and immediately started the observation. We do not see any
optical transient in the GRB errorbox down to the foillowing
3-sigma limits:

mean time after GRB   exposure    limit    filter
       7m20s            70s       17.8       Rj
       19m5s           270s       18.9       Rj

Note that BOOTES-IR is still in comissioning phase operating
without the IR camera.
