Berkeley Scientists Discover an "Instant Cosmic Classic" Supernova

A supernova discovered yesterday is closer to Earth - approximately 21 million light-years away - than any other of its kind in a generation. Astronomers believe they caught the supernova within hours of its explosion, a rare feat made possible with a specialized survey telescope and state-of-the-art computational tools.
The finding of such a supernova so early and so close has energised the astronomical community as they are scrambling to observe it with as many telescopes as possible, including the Hubble Space Telescope.

Astronomers last night discovered a bright supernova, otherwise known as an exploding star, and say it is the nearest of its type observed for 40 years.
The supernova was spotted in the Pinwheel Galaxy, M101, a spiral galaxy a mere 21 million light years away, lying in the famous constellation of the Great Bear (Ursa Major).
The supernova, dubbed PTF11kly, is still getting brighter, and the team's best guess is that it might even be visible with good binoculars in ten days' time, appearing brighter than any other supernova of its type in the last 40 years.

A magnitude 17.2 (and rising) type Ia supernova was discovered on the 24th August, 2011, by the Palomar Transient Factory (PTF), in the Pinwheel Galaxy (Messier 101) in the constellation Ursa Major.
The supernova is located 58.6" west and 270.7" south from the center of the galaxy.
The galaxy also hosted supernova 1909A, 1951H and 1970G

Position (J2000): R.A. 14 03 05.80 | Dec. +54 16' 25.3''
z = 0.000804
