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 5676Loading...
 
 ), discounting the 10s settling image. At the
position of the XRT error circle (Page et al., GCN 5681Loading...
 
 ) 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
