Abstract:
We present ultraviolet (UV) observations of supernovae (SNe) obtained
with the UltraViolet/Optical Telescope (UVOT) on board the Swift
spacecraft. This is the largest sample of UV light curves from any
single instrument and covers all major SN types and most subtypes.
Description:
The Swift UVOT has observed 45 SNe (21 Ia, 13 Ib/c, and 11 II) between
2005 March and 2007 August.
