The Ultraviolet/Optical Telescope (UVOT) on board the Swift satellite started observing Supernova 2010jr in ESO 362-18 (CBET #2545) at 2010-11-15.6 UT. The following UVOT magnitudes were measured: uvw1 [lambda_c = 260 nm] = 15.9±0.1 (315 s), uvm2 [lambda_c = 225 nm] = 16.0±0.1 (364 s), uvw2 [lambda_c = 193 nm] = 16.2±0.1 (630 s). These magnitudes are on the UVOT photometric system (Poole et al. 2008, MNRAS, 383, 627) and have not been corrected for extinction. Compared to other SNe of this type (CBET #2548), these UV magnitudes are on the brighter end of the distribution.
