Swift Ultraviolet/Optical Telescope (UVOT) began observing the type-Ia SN 2007sr in the Antennae (NGC 4038) (ATel #1337, CBET #1172, #1173, #1174,) on 2007-12-20.81 UT. The following UVOT magnitudes were measured: v = 12.90.1 (208 s exposure time), b = 13.20.1 (208 s), u = 13.50.1 (216 s), uvw1 [181-321nm] = 15.10.1 (834 s), uvm2 [166-268 nm] = 17.40.1 (610 s), and uvw2 [112-264 nm] = 16.50.1 (834 s). These magnitudes are on the UVOT photometric system (see Poole et al., 2007, MNRAS, accepted [astro-ph/0708.2259] ) which in the optical is close to the Johnson UBV system. They have not been corrected for extinction.

Further Swift observations are in progress.
