Nice find Op.

I wonder why it would change color?


I'm not convinced that it's as much a change in color as it is a change in signal to noise ratio. The comet is finally getting high enough over the horizon prior to twilight that you can collect images with very good signal/noise ratios and get good color data. My September 28th image was the first time I collected what I would consider to be reliable color data on the comet. That's mostly driven by how high over the horizon the comet is and how long I can collect images at good altitudes before twilight.

You can just start to see a touch of green hue to the comet.

Channeling HG Wells this morning?

Oh, my god... Oh, wait, it's a water tower, not a Martian tripod...

Well, if in the coming weeks it turns blue, I'll believe the Hopi were right and start bugging out.


Bug out to where? According to the prophecy there will be no safe place to go to.

"And this is the Ninth and Last Sign: You will hear of a dwelling-place in the heavens, above the earth, that shall fall with a great crash. It will appear as a blue star. Very soon after this, the ceremonies of my people will cease.

So the probability of it having (CN)2 in it is increasing. Doesn't the earth pass through it's tail? The earth will glow green like my eyes


I doubt if that enough cyanogen will enter the atmosphere to hurt us though. I'm pretty sure that by the time we get into the tail there will nothing other than a lot of tiny green meteor showers.

I keep hearing that we will pass underneath it's tail, not through it.

But then again, the guy that says "Hey Y'all! Watch this!" while others are filming was pretty confident too. LOL

Wouldn't it be great if we were treated to such a view as they were for the great comet of 1680!

The tail is now mucous?
send it some mucinex.

Well,now,you surely didn't expect me to give out my intended location,did you ?

ISON has no colour to begin with. The colour is from UV emissions from the coma of ISON creating the green by ionisation of oxygen in Earths atmosphere. If it changes to blue, then it is because of changing ionisation levels in the coma, due to electrical and not thermal changes, and it is nitrogen in Earths atmosphere that is then being energised.

There is no heat from the Sun to warm up the comet. Too bad that some of the ISS instruments are shut down, but even if everything was normal up there, they would not be looking at ISON, as there is nothing to see, by eye, or with a Nikon, unless ISON at some time will pass through the Earths atmosphere at a convenient time for it to be imaged, and the only previous comet images from the ISS require Earths atmosphere to make them visible to a Nikon.
Lovejoy.

www.universetoday.com...

The image from Hubble of ISON was taken with the F606W (V) filter, which is a wideband visible wavelength filter, so the colour is only arbitrary.




This image was originally black and white and recorded only overall brightness. These brightness values were translated into a range of bluish hues. Such color "maps" can be useful in helping to distinguish subtly varying brightness in an image.


imgsrc.hubblesite.org...

But also you must remember that Hubble uses some very complex optics, and was and still is a military operation, and that a regular camera would not be able to capture such an image from space. Becuase of technical limitations, ISON in Celestia does not show a label, so I can not easily tell when it will pass through Earths atmosphere as viewed from the ISS, but right now ISON is close to Mars, and so with a telescope (if they had one on the ISS) it would be visible at some point through Earths atmosphere. I havent actually seen an image of Mars from the ISS though.

@The Hopi Blue Kachina / Red Kachina Prophecy

Also depends if there is a reddish celestial further out following in consideration of the HOPI prophecy...

Green is the color of cyanide when the gas is excited by the sun(like an aurora around the comet).High electrostatic voltage also make cyanide gas glow green. (comets have a high electrostatic potential charge ) . So this may be the comet in the Revelation of St. John, called WORMWOOD.Arounnd the turn of the last century , wormwood was used to make Absynthe.

My September 28th image was the first time I collected what I would consider to be reliable color data on the comet. That's mostly driven by how high over the horizon the comet is and how long I can collect images at good altitudes before twilight.

Great pic ngchunter! What time and what scope?

We might pass through some of the dust it leaves behind, but we will not be passing through the tail.

Thanks! That was imaged from about 5:50 am ~ 6:24 am eastern on September 28th. I used 2 minute exposures with an Orion ST-80 piggybacked on the LX200. I stacked the images aligned on the stars, then again aligned on the comet, then composited the two resulting stacks together to show both the comet and stars sharply.

as different minerals, elements or chemicals burn up on the comet surface you will see different colors in the Coma head or tail


Yellowish Green comet color suggests that Borax is being burnt off the comet
A Green comet indicates that Copper Sulfate or Boric Acid is being released & combusted

if ISON is an accreted ball of ices & stuff from out there in the Oort cloud...theres no telling what sized deposits of different minerals or chemicals will be outgassing from one minute to the next...

but a solid mass of some chemical in the water-ice should render the comet an individual color all the way in-&-out of the inner solar system as it burns off its gasses in the journey around our Sun


'green' is good in one respect but the death omen is 'pale' which is a mix of yellowish-green

the Mayan end-of-age prediction of the return of the 'green bird' might be meaning comet ISON...
but i guess all that is thrown out after 21 dec 2012

" burn up on the comet surface" if there if neither, friction,as Space is an absolute Vucumn,, nor oxygen, needed for Combustion,,,"burn up " makes no sence. ??

I only said that its weird both events happening at almost the same time, nothing more nothing less ...


Yes just the regular random ISON drivel, where normal and expected phenomena are treated like shocking mysteries, and unrelated topics are connected because when viewed together there is more hint of doom.

I am going to do an attempt if it stays clear with my 5" in the next day or two.

Maybe half of it crashes on Mars because of its really really close flyby , then we have to set up the first manned mission to Mars asap to retrieve those bills...
