NASAs Hubble Space Telescope provides a close-up look of Comet ISON (C/2012 S1), as photographed on April 10, when the comet was slightly closer than Jupiters orbit at a distance of 386 million miles from the sun.

Looks like Nov. 6th - 26th will be the best viewing dates before it goes around the opposite side of the Sun.
