COMET C2012/S1 ISON : COMA/TAIL OF OVER 64,400 KM [UPDATE]

So you're saying this thing is bigger than the Earth? Earth's diameter is about 7,900 miles? It should be causing some gravity disturbances by now. Where's our resident astronomer, Astro? I'm sure he'll have something to say.

ALL IM SAYING IS THAT WHEN MEASURED , [YOU CAN DO IT YOURSELF] WAS BETWEEN 17,000 AND 23,000 KM.. OFFICAL ESTIMATES ARE STILL 5 KM....

AND YES THAT WOULD BE HUGE....

I "DID" C2010/X1 ELENIN SO IM NOT PRONOUNCING DOOM .. BUT..

THE OBSERVATIONS ARE NOT CRYSTAL CLEAR WITHIN THE CONTEXT OF OTHER DATA ...
I GUESS NOW WE WATCH N WAIT.. WITH THIS THREAD .. CAUSE I CAN KEEP IT ON SUBJECT

I DON'T MIND FACTS BUT REMEMBER I WILL EDIT, IF IT BECOMES NECESSARY

MORE [BUT OLDER] IMAGES

[link to www.astronomie.be]

[PLEASE POST]
MORE IMAGES WITH SCALE
SCIENTIFIC OBSERVATIONS
OFFICIAL REPORTS

It helps to send me a PM. First question for the OP, why the hell are you measuring the image in "millimeters?" Why aren't you astrometrically solving an image of the comet to truly calibrate the image and measure it in terms of arcseconds per pixel? And secondly, what is it that you think you're measuring, the physical nucleus? You're not. [link to books.google.com]

'The sky will display two suns' Nostradamus prophecy December 2013. Pope Francis will leave Rome during that time . It's obviously a huge comet.

You're not measuring the physical nucleus RPhunter. That's where the 5 km figure comes from. I suggested 20km earlier, guess I was being generous, but the point is the physical nucleus is nowhere near "17,000km" or "23,000km" that WOULD cause massive detectable perturbations of the planets' orbits. You're measuring the expanding cloud of dust around the comet.

OMG! Look! It's a lens flair!

:noblac:

Travelling at 11km/sec the last time I checked (please correct me), I dare say any "dust" would have been long gone, unless of course it has demonic claws to latch itself into rock. Ionized gas is the cloud, dr.

Relative to what?

The dust is constantly leaving the comet. And yes, it's dust, hence all the dust from comet Wild 2 in this piece of aerogel:

I MEASURED IT BECAUSE I CAN DO THAT ..

YOU DIDN'T READ THE THREAD MY DEAR ASTRO.....
I DID ...

IN THE NASA IMAGE LISTED THERE IS A ARCMINUTE SCALE

I MEASURED IT 60 MM PER ARCMINUTE

ISON IF NOT GENERATING SOLAR DRIVEN COMA MEASURED BETWEEN 6 AND 9 MM
OR .1 TO .15 ARC MINUTES THEN I DID THE MATH

Its both dust AND gas, being steadily released.

Yes! Both AsstroShill and Shillcyon Dayz are urgently needed on this thread!

Again, why are you measuring it in "MM?" You should first determine how many arcseconds (or arcminutes) per pixel and then measure based on that for accuracy.

Yes, I read your thread, your methodology is questionable.

I'm sorry I'm having trouble parsing your english there.

This could evolve in an interesting discussion...

I LOOKED AT THE LINK .. EXCELLENT BOOK LINK .. BUT I DONT HAVE THE PROCESSING CAPABILITY TO PREFORM A LARSON-SEKANINA FILTER .. DO YOU?

:catshow:

Then again, it may not...

IRIS FREEWARE LINK BY THE WAY

Not necessarily Larson-Sekanina specifically, but I do have the ability to process cometary images with a rotational gradient filter using IRIS. Not sure what algorithm it uses, but it is quite effective if used properly.

Only question is why is doctor astro taking so much care about
figthing every comet ison is nibobo thread?

Bump for truth

Why do you care that I care?

he cares because he likes truth and also likes to help us to be better informed. You, a passion and lo e to do something for the human race, once well understood its a blessing to do.

TO PREVENT PEOPLE WHO ARE CHALLENGED AT REASON AND LOGIC FROM PANICKING ... I WANT TO MAKE THIS CLEAR IF I MEASURED THE COMA [ACCURATELY I MIGHT ADD] ILL SAY SO WHEN I SEE PROOF.

FROM THIS ANGLE WE CAN'T "SEE" THE TAIL FOR SOME TIME YET
SO WHAT ASTRO'S LINKS SUGGEST IS TO FILTER THE HEAD ON SHOT FOR ROTATION , AND SEE IT IT SHOWS THE COMA IN RELATION TO THE NUCLEUS ...
NASA MADE AN ESTIMATE .. I MEASURED IT .. WE AR STILL EXPLORING FACTS AT THIS TIME

he cares because he likes truth and also likes to help us to be better informed. You know, a passion and love or urge to do something for the human race, once well understood its a blessing to being able to do.

i care if you care because if you care it must be something to take care of for bad,
you know shilling work, the plot thickens...
