  The wide range of UV extinction properties in the Small Magellanic Cloud
(SMC) probably traces the effects of star formation on interstellar dust. The
Swift UVOT, with its three UV filters (centred at 1800, 2200 and 2500 A
respectively) and three optical filters, is an ideal instrument to map this
extinction. We present preliminary results of six-band photometry in a ~ 3.3
arcminute square field in the SMC. Fitting the resulting optical/UV spectral
distributions with a dust model, we estimate the depths of extinction for 53
stars and use this to map the distribution of dust in the observed field. We
briefly discuss the relevance of this study for star forming galaxies,
including the hosts of Gamma-Ray Bursts.
