Comet ISON is visiting the inner solar system and is set to put on spectacular views for the Northern Hemisphere across November and December as it heads towards the sun.

It may prove to be brighter than any comet of the last century - visible even in broad daylight - and this may end up being its one and only trip to the solar system, as its trajectory may see it plunge into the sun in a fiery death.
December 2013. This is likely to be the best month to see Comet ISON, assuming it has survived its close pass near the sun intact. The comet will be visible in the morning sky before sunrise at its brightest; later in the month, it?ll appear in both the morning and evening sky (because it will have travelled so far north on the sky?s dome that it will become circumpolar).

However, don?t wait until late December, for ISON to appear in the evening sky. As ISON?s distance from the sun increases, it?ll grow dimmer.

The crescendo of the apparition will likely occur between December 10th and 14th, when the comet will be best seen just before dawn after the moon sets. Although little or perhaps nothing of the head will remain, the huge tail will loom in the northeastern sky. Almost evenly illuminated over its length, this rapidly fading appendage could [span] almost a quarter of the heavens as seen under good, dark observing conditions.
