As November opens, Comet ISON MIGHT have brightened to naked eye visibility, or it might not quite have reached that level of brightness yet. It should certainly be visible with a pair of binoculars to anyone who goes to a site with a dark sky unspoiled by light pollution This will be the most exciting time of the whole apparition I think, as each day more and more people get to see it.
On that subject, please note, YET AGAIN, that the tails shown in these images should NOT be taken as accurate, for either their length or brightness. They were generated by planetarium software which can’t accurately predict WHAT a comet’s tail will look like, so just use these images to guide you to WHERE to look at the times given, and take the appearance of the tail on the images with a large pinch of salt, ok?
That will be an irresistible scene for astrophotographers with a wide angle lens and a clear, dark, un light polluted sky… A little later the sky will be brighter, but if ISON has a tail by Nov 1st there should be some truly lovely pictures to be taken before dawn on Nov 1st, with that thin crescent Moon beneath it…

Have you forgotten Hale-Bop?

It haunted my front door for ages....comets have never been anticipated as "benevolvent manifestations"

I, for one, am not excited to see Ison. But, just me and my 2 cents.

Thanks for the info and I enjoy reading about this comet. I usually stick with the political side of ATS but for some reason this comet has peeked my interest.
I have a question maybe someone could answer do we know what the mass of this comet is? I really know very little about this kind of thing and I am sorry if this question is stupid.edit on 24-9-2013 by SubTruth because: (no reason given)
The Jan. 30 UVOT observations reveal that ISON was shedding about 112,000 pounds (51,000 kg) of dust, or about two-thirds the mass of an unfueled space shuttle, every minute. By contrast, the comet was producing only about 130 pounds (60 kg) of water every minute, or about four times the amount flowing out of a residential sprinkler system.
While the water and dust production rates are relatively uncertain because of the comet's faintness, they can be used to estimate the size of ISON's icy body. Comparing the amount of gas needed for a normal comet to blow off dust at the rate observed for ISON, the scientists estimate that the nucleus is roughly 3 miles (5 km) across, a typical size for a comet. This assumes that only the fraction of the surface most directly exposed to the sun, about 10 percent of the total, is actively producing jets.

Thanks for the the reply. I wondered how they could plot the path without knowing the exact mass. Also could the sun effect this by burning off mass. And could that change it's path?
