report:

"Following the detection of GRB 051001 by SWIFT 
(Krimm et al. GCN 4052), we have imaged the              
entire error box with the 0.6-m (+MOA camera) at 
Mt. John Observatory in wide R- and B-band filters 
(8 x 300-s each) starting on Oct 1.48 UT (i.e. 
45 min after the event).  We do not detect the
object reported by Rol et al. (GCNC 4053) within 
the SWIFT/XRT error box (Moretti et al. GCN 4051) 
down to R about 21.5 ."
