SN 2005bcwas aType Ia supernova^[3]occurring in thebarred spiral galaxy NGC 5698,^[1]located in the northernconstellationofBoötes.SN 2005bc was discovered on 2 April 2005 by LOSS and independently by Tim Puckett and L. Cox.^[4]It was positioned at an offset of4.6″east and7.5″north of the galactic nucleus.^[1]Thesupernovawas atmagnitude16.4 at discovery, and quickly rose to a peak magnitude of around 15.3 (in visible light) just over a week after discovery. It showed an expansion velocity of12,000 km/s.^[3]By mid-May, the supernova had faded to 17th magnitude.

The host galaxy, NGC 5698, along with the supernova lie approximately 129 millionlight-years(~40 millionparsecs) from Earth.^[2]As the supernova was of Type Ia, its progenitor star was acompact white dwarfstar that exceeded theChandrasekhar limit.
