The path of ISON
Comet ISON is nearing its perihelion, the closest point to the Sun (take place on November 28th at 18:24:57 UTC) and if it will indemnify the His meeting with our Star should return visible in our skies since December 3.

WOULD ALREADY ‘FREMMENTATA? However, we hear news very encouraging considering that its core according to some may have already disintegrated, for others it might disintegrate shortly after the critical point set in the perihelion. Confirming the news coming from Spain, where researchers millimeter IRAM telescope reported yesterday a decrease of molecular emission of Comet ISON : The decrease recorded between 21 and 25 November, it could indicate that the activity of the nucleus is falling or that do not even exist anymore.
According Battams, NASA: We are reading reports online where you says that the molecular emission of the comet decreased drastically in the meantime the production of dust seems to be immense. This may indicate that the core is completely fragmented releasing a huge amount of dust, making the issue subside. The fragmentation of the nucleus has always been one of the risk factors associated with this comet, so if this is what happened, it’s not a surprise. However, these reports are new, and though undoubtedly valid, we must continue to observe the comet to be sure of what is happening. Remember: Comet ISON is a grazing comet, which comes from the Oort Cloud, and the last time we saw something like that was EVER! In addition, a grazing comet from perihelion to three days has never been studied in so much detail.
skeptical even NASA in a statement that states that ISON pussy little more than a million kilometers from the surface of the sun, about 30 times closer to the passage of the comet Encke in 2007. They also point out that in 2007 the Sun was near the solar minimum and then was poor the same active the Sun, while the Sun is now in full swing, very close to the peak of the solar cycle and therefore are more frequent eruptions.
This reduces the hopes that steps ISON indemnify its passage around the Sun, but even in these cases the hope is the last to die.
While one side is feared the fate of ISON, other scientists expect with trepidation that the comet is invested by a powerful CME (coronal mass emission), that generated by a blasting should not affect the core of Ison, seen that the gas inside is not very dense, but would study its effects on the tail of the comet.
