A. Breeveld (MSSL/UCL) and J. Cannizzo (NASA/UMBC) report on behalf of
the Swift/UVOT team:

The Swift/UVOT began taking data on 2006-10-02, 129s after the burst
(Cannizzo et al., GCN 5676), discounting the 10s settling image. At the
position of the XRT error circle (Page et al., GCN 5681) there are no
new sources. In the summed UVOT images we obtain the following 3 sigma
upper limits:

  Filter    T_range(s)   Exp(s)    3-sig UL (mag)
       v     129-7107    1283      20.32
       b     607-6697    412       20.63
       u     582-12911   1095      20.87
      w1     559-12244   1337      21.11
      m2     534-11337   1354      21.41
      w2     622-6902    432       21.19

These magnitudes are not corrected for the expected extinction of
E(B-V)=0.046
