I think you folks are being pretty hard on the media. I think they were pretty fair, there was a lot of "if this" or "maybe." I would rather the media hype it and get people out there looking up then the opposite.... an impressive object/event that gets totally ignored.




The media deserves some harsh words. Here's an early article.

I've been doing outreach for decades, and I don't think we do the hobby any favors by getting people excited about events that turn out to be duds. Better to be pessimistic and have people pleasantly surprised than to disappoint. With today's Internet, Twitter, and other very immediate ways to communicate, it's easy to get the word out late in the game.

Clear skies, Alan




Alan,
Yes that article you linked to might be a little bit hyped, but it also states that ISON might be a great comet. I think claiming ISON would be bright is a fair description, it was bright coming in especially in the last few weeks. No it wasn't naked eye, but I found it with my 10X50s and was impressed. I think what makes ISON amazing is the science of the object and lets also admit the nail baiting that has been done over the last 24 hours of it being declared dead and now maybe still alive. That makes for a good story.

If you can see a comet in 10X50s it is pretty bright.

I will gloat because I was right. And, I was using my brain, what little there is of it, rather than just guessing.

The fundamental mistake that was made by the astronomers on the NASA presentation was that they had faith in an instrument that was not appropriate to the observation they were trying to make. In addition, Phil Plait misinterpreted the comet's Ikeya-Seki-like shape going in as indicating the lack of a nuclear condensation, as though the comet had simply gone to bits, which was obviously incorrect for anyone who has studied Sun-grazing comets and is familiar with how they generally look. But, hey, it was "cool."

As time goes on, I find that I have more respect, in general, for our own advanced amateurs, people like DL, JB, TL, etc., than I do for many so-called professionals. It is getting to the point where I do not believe some of these PhDs know which way is up or could operate a telescope on their own. And our popularisers have fallen greatly in quality and act in the way necessary to achieve some measure of fame, which is sad.

To heck with ISON, I'm not sure I'm going to survive all this back and forth! Such an emotional roller coaster...

Just a reminder.
From the Cloudy Nights' terms of service:

Posting of NASA/NOAA images and the images of other government agencies is permitted in context provided the following conditions are met: 1) The respective agency permits that sort of use for the photo, 2) the photo is clearly labeled/credited, and 3) a link is provided to the site from which the photo was obtained.

With all of the excitement going on now I will merely state that the images of ISON and the occulted sun in this thread were from NASA and the SOHO observatory. Since the NASA site won't respond for me I cannot provide a link.

Things do not look very promising.

November 29, 10:30 p.m. EST: A fading ghost. At 19:54 UT Filip Fratev (Bulgarian Acadamy of Sciences) wrote, "ISON [has] started to fade.... [In] the last four hours it faded by more than 2 magnitudes and obviously is less bright... I estimated the comet to be between 2.6 and 3.1 magnitude now."

Four hours later Karl Battams of the Comet ISON Observing Campaign tweeted, "We can't tell if #ISON is in one piece or many. It's about mag 5 now and fading."

That's much fainter than the revised IAU magnitude figure for today's UT date.

For an amateur astronomer, yes. For the general public, decidely no.

That's insane, that sounds incredible!!


... Ralph

Out with my C14 and 7" refractor right now at 7000ft with a group of astronomers in the dark blue color zone, so I'm trying to not let them see me getting these updates!! But thanks!!

Will it be naked eye visible? When? How bright?
This is definitely the toughest question but also the most frequent. We still don't know if it will be naked eye but based on its current brightness in the LASCO images - which is around magnitude +5 and fading - it does seem unlikely that there will be much to see in the night sky. I suspect that some of the outstanding astrophotographers around the world will be able to get something, but I doubt it will be as spectacular as before perihelion. I hope I'm wrong though.

With all the ups and downs as to weither ISON will survive all I can say is "Lets just wait and see."

Don't fret. Lovejoy is a wonderful comet, and the Big Dipper's handle is pointing right at it. It is a naked eye object and has a nice tail.

The only naked eye comet I've ever seen was Hale-Bopp. I lived in Toledo, OH then and found a very dark site just over the MI line to observe and photograph it.

ISON was obviously an extra in the Bond film "You only live twice"

I also think David Levy wasn't quite right that "Comets are like cats ..." - he missed the fact that cats have nine lives but comets have one and only occasionally have two with the second "life" being rather brief (e.g. this one and C/2011 W3 ...)

.....and another one bites the dust!

If Sol was a thinking entity he might have thought "how long can you stand the heat?"

Fitting I suppose ... what with the guitarist having an Astrophysics PhD and a habit for creating 3D comet images
