Comet ISON prospects, quite literally, are getting brighter by the day.

It is intact and is becoming more ‘active’, i.e., spewing out more gas and dust which is what leads to the coma and tail, by the minute.

Right now it is travelling at more than 10 miles PER SECOND. That is in excess of 38,000 miles per hours. So it is getting closer to the Sun at a very fast clip.

Ameteur astronomers using backyard telescopes are capturing some amazing pictures. Check this one from October 5, from Austria (that is in Europe).

On November 2, 2013, i.e., next week, it will cross Earth’s orbit for the first time, i.e., inbound (towards Sun) crossing. Check this post for orbital diagram.

But, on that day Earth is way off to the right — 112 MILLION miles away, that is 1.2 x the Earth-Sun distance.

So, we will not be able to see Comet ISON, naked eye, on November 2.

The EARLIEST possibility for a potential glimpse is November 17 — some of this also having to do with moonlight getting in the way.

Closer to the 17th, as things become more clear, I will post an update.

Enjoy.

It might not be the ‘Comet of the Century’, but it is still on track to be one heck of a comet.

Looking good. Very promising. I am still very hopeful.

I never lost faith. I knew that the naysayers where just seeking their 15 minutes of publicity.

Should be naked eye visible by the November 10, 2013, I reckon.

Judging by my book sales curiosity is piquing if not peaking.

I am doing presentations on ISON at the Taylor Community (in Laconia) and at the Alton Public Library during the first week in November. I will post more details soon. So, if you are interested, come to one of those. Would love to see you. I am also speaking at Portsmouth Rotary, but that is after Thanksgiving.

A couple of folks, yesterday and today, were inquiring as to when Comet ISON, C/2012 S1 (ISON), will be visible over New Hampshire.

I assume they meant naked-eye visible. The comet has been visible telescopically for just over a year — with ~9 week hiatus between May – July when the glare of the Sun was between us and the comet.

It won’t be naked eye visible, even if you have exceptional eyesight till later this month, i.e., October. Early November is more promising. To start with it might just be visible at dawn. After perihelion, assuming it survives its very close sungrazing passage, it should be visible, vividly, throughout the night during December — with luck.
