- REDIRECT Template:Infobox astronomical event
SN 2005bc was a Type Ia supernova[1] occurring in the barred spiral galaxy NGC 5698,[2] located in the northern constellation of Boötes. SN 2005bc was discovered on 2 April 2005 by LOSS and independently by Tim Puckett and L. Cox.[3] It was positioned at an offset of Script error: No such module "val". east and Script error: No such module "val". north of the galactic nucleus.[2] The supernova was at magnitude 16.4 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 of Script error: No such module "val"..[1] By mid-May, the supernova had faded to 17th magnitude.
The host galaxy, NGC 5698, along with the supernova lie approximately 129 million light-years (~40 million parsecs) from Earth.[4] As the supernova was of Type Ia, its progenitor star was a compact white dwarf star that exceeded the Chandrasekhar limit.
