Following the announcement of PSN J17492705+3608360 in UGC 11000 (Zheng & Filippenko 2015 ATEL#7345) we requested observations with Swift's Ultraviolet/Optical Telescope (UVOT). Observations began 2015-04-05 13:47:14 UT. The following UVOT magnitudes were measured: v = 15.96 +/- 0.09 (79 s exposure time), b = 16.09 +/- 0.06 (157 s), u = 14.85 +/- 0.06 (157 s), uvw1 = 14.70 +/- 0.06 (315 s), uvm2 = 14.44 +/- 0.06 (825 s), and uvw2 = 14.60 +/- 0.06 (381 s). These magnitudes are reduced using the method outlined for the Swift Optical Ultraviolet Supernova Archive (SOUSA; Brown et al 2014, Ap&SS, 354, 89, arXiv:1407.3808) on the Swift/UVOT Vega-based photometric system (Poole et al. 2008, Breeveld et al. 2011). Galaxy light has not been subtracted, but the supernova is much brighter than the underlying galaxy light. The UV-optical colors are similar to those of young core-collapse supernovae.
