SN 2013fs is a supernova, located in the spiral galaxy NGC 7610, discovered at Palomar Observatory in October 2013. Within 3 hours of discovery it was observed in ultraviolet and X-ray wavelengths, among others.[2] These are the earliest such detailed observations ever made of a supernova.
The star that produced SN 2013fs was a red supergiant, probably between 8 and 10 times the mass of our Sun and no more than a few million years old when it exploded.[2] The star was surrounded by a relatively dense shell of gas shed by the star before it exploded.[2] Radiation emitted by the supernova illuminated this shell, which had a mass of approximately one-thousandth the mass of our sun, and its outer fringe was about 5 times the distance of Neptune from our sun.[2]
