"The wide field camera of the FRAM telescope, located 
at Pierre Auger observatory in Malargue, Argentina,
followed the INTEGRAL GRB 070311 (Mereghetti et al. GCN
6189, Guidorzi et al. GCN 6192, Covino et al. GCN 6190,
trigger #4166).

20s R-band (lambda_eff = 640nm) images were obtained 
starting 46.8s after the GRB (32s after receiving the
notification).

We do not detect any new source down to the limiting
magnitude R=~15.0."
