Excitement continues to rise among both professional and amateur astronomers  about Comet ISON, which on Nov. 28 of this year might become one of the  brightest comets ever seen, outshining such recent dazzlers as Comet Hale-Bopp  (1997) and Comet McNaught (2007).

Fortunately, Comet ISON was discovered 14 months before this perihelion passage — its closest point to  the sun — while still distant and faint, thus giving observers time to plan.  Another major advantage is that this fine object will be favorably placed for  viewing, first in the morning sky before perihelion passage on Nov. 28, and then  both in the morning and evening sky afterward.
