We report on Swift Ultraviolet/Optical Telescope (UVOT) observations of SN 2006bc (Martin CBET #446) obtained on 2006-03-27.93 UT.

A new object is detected at R.A. = 7h21m16s.50, Decl. = -68o59'57".3 (equinox 2000.0) when compared to DSS images, consistent with the position reported by Martin (CBET #446). UVOT magnitudes are B = 17.6, U = 16.7, UVW1 [181-321 nm] = 17.4, and and UVW2 [112-264 nm] = 18.0. Statistical and systematical errors are 0.1 mag each. Comparing the U-B color with other SNe from Poznanski et al. (2002, PASP, 114, 833) shows that the SN is approx. one magnitude bluer than observed in the displayed SNe. The similarity of the colors with the type II-P SN 2005cs (Brown et al. in prep.) and the Type II SN 2006at (Brown & Immler ATel #771) at similar epochs indicate that SN 2006bc is a Type II SN.

Further Swift observations are scheduled.
