B.A. Rowlinson and K.L. Page (U. Leicester) report of behalf of the
Swift-XRT team:
Swift-XRT completed a 10ks follow-up ToO obsevation of GRB 090118
(Copete et al. GCN Circ. 8825) approximately 250ks after the burst.
These observations confirm the previous Swift-XRT observations

with a decay slope of alpha=0.61 +/- 0.3. This source is confirmed as
the afterglow.
