BIG GREEN COMET: The icy nucleus of comet 103P/Hartley 2 measures no more than a couple of kilometers across. That tiny nugget, however, is surrounded by an vast atmosphere of gas more than 150,000 km in diameter--about the same size as the planet Jupiter! And it's coming our way. Amateur astronomer Nick Howes sends this picture of the approaching comet from Cherhill, WIltshire UK:
"I photographed the comet on Oct. 1st using a 4-inch refractor," says Howes. "Four hours of exposure time revealed not only the comet's vast green atmosphere but also an emerging tail." Howes describes the processing of the data here.
At present, the comet is a 7th-magnitude object best seen through telescopes. (We recommend the Comet Hunter.) The view will improve, perhaps even to naked-eye visibility, as the comet glides by Earth only 11 million miles away on Oct. 20th.
Two weeks after Comet Hartley has its close encounter with Earth, NASA will have a close encounter with the comet. The Deep Impact/EPOXI spacecraft is hurtling toward Comet Hartley now, and on Nov. 4th it will fly 435 miles from the comet's active icy nucleus. The encounter will mark only the fifth time in history that a spacecraft has been close enough to image a comet's core.
Until then, amateur astronomers can monitor the comet as it glides through the constellation Cassiopeia in the evening sky. A finder chart from Sky and Telescope shows the comet passing by a variety of stars and deep-sky objects, offering many photo-ops in the nights ahead.
COMET HARTLEY 2 UPDATE: Some observers are reporting that comet 103P/Hartley 2 has reached the threshold of naked eye visibility. “I was able to see the comet last night under very dark and transparent skies,” says Kevin Koski of Cascade, Wisconsin. Veteran observer Mike Holloway of Van Buren, Arkansas, adds that “the comet was almost ‘naked eye’ with averted vision on Oct. 2nd.” In the nights ahead, telescopic observers are encouraged to lift their eyes from the optics to attempt a sighting.
APPROACHING COMET: Green comet 103P/Hartley 2 is approaching Earth for a close encounter on Oct. 20th. At that time, the comet will be only 11 million miles from Earth and should be dimly visible to the naked eye from dark sky sites. It already looks great through backyard telescopes:
Approaching COMET HARTLEY the blue star according to the Hopi prophecy?
Hmmm....That IS green isn't it..........
HG Wells, The War of the Worlds
At midnight on the twelfth of August, a huge mass of luminous gas erupted from Mars and sped towards Earth. Across two hundred million miles of void, invisibly hurtling towards us, came the first of the missiles that were to bring so much calamity to Earth. As I watched, there was another jet of gas. It was another missile, starting on its way.
And that's how it was for the next ten nights. A flare, spurting out from Mars - bright green, drawing a green mist behind it - a beautiful, but somehow disturbing sight. Ogilvy, the astronomer, assured me we were in no danger. He was convinced there could be no living thing on that remote, forbidding planet.
"The chances of anything coming from Mars are a million to one," he said. "The chances of anything coming from Mars are a million to one - but still they come!"
The science websites are all a-flutter with the greeen comet. Yet, none cater to the amateur viewer by giving a simple “direction and elevation above the horizon” explanation for viewing.
Anyone here have that basic info available?
Cassiopeia should be nearly overhead about midnight. Looks like a “W”
This is interesting....
YES. . . and. . . NO.
NOTE: “www” is the acronym for world wide web and is normally used as the prefix, or first node of the Internet domain names, such as www.av1611.org
FIRST. . . The YES.
How to get 666 from www?
The Hebrew and Greek alphabet does not have separate characters or alphabets for numbers and letters. Letters are also used as numbers. So each letter is a numerical value.
The Hebrew equivalent of our “w” is the letter “vav” or “waw”. The numerical value of vav is 6. So the English “www” transliterated into Hebrew is “vav vav vav”, which numerically is 666.
Remarkable that such a small mass can drag such distant particles along in its gravity field.
As recorded by St John the 'mark' looks like the Greek letters Chi, Xi and Sigma-Tau (a ligature of Sigma and Tau).
More usefully, here is an image of the so-called 666 from the Codex Vaticanus of Revelation which dates to around 350 AD - 200 to 300 years after John wrote Revelation. These marks are often - and erroneously - interpreted as '666' when they are in fact a simple image.
Let's look at that again:
Is there anything that looks like that? What could that be? I'm not sure, but it looks awfully familiar ...
That design is common in Islam. It is a pair of crossed swords next to the Bismallah - the Name of Allah.
It's not very clear, but you can just make out the X-shaped swords and the middle symbol on this piece of material:
And if we pull out a bit, we get the whole thing - this is an image of a armband belonging to Hamas:
I got these images from this PDF. It's well written and worth reading in its entirety. The Bismallah - the Name of Allah - worn on head and arm by fanatical jihadists the world over - is the Mark of the Beast.
Hope this is helpful
Those particles have been blasted off the comet by the solar wind, forming (depending on their size and type) its tail and halo. They won't stay with the comet.
Actually, here in suburban Chicago, Cassiopeia looks like a single bright star (naked eye). I can make out some whole constellations with my binoculars.
I’m hoping to use them to see beyond some of the “light pollution” and pick out Hartley.
Thanks for posting!
Certainly interesting and worth paying some attention to, imho.
Comet - It will make your teeth turn green
Comet - It tastes like gasoline
Comet - It will make you vomit
So get some Comet, and vomit, today
Indeed. The fact that the comet is green reminded me of the "green mist" which trailed the capsules launched by the Martians.
Of course, the segment of the intro I quoted was narrated by the late Richard Burton. Lead vocalist for the sung portions was Justin Hayward of the Moody Blues.

Pretty unusual, it doesn’t sound like outgassing but
what kind of mass would you need to hold that atmosphere
in place, to travel along with the nucleus??
Nully, check out # 15.
That makes sense (unlike most of the rest of this thread). Thanks.
It’s not being held in place. It is diffusing out into space.
Correct you are.
And, Parson Nathaniel was none other than Phil Lynott, lead man of Thin Lizzy.
I had that LP when I was a lad, and most recently, found it online, and it is securely on my Ipod now....ULLA
Still doesn’t make sense, a kilometer sized object is
not going to have enough mass to hold an atmosphere
even temporarily, where did it come from?
That’s a bit like asking where the water around an ice cube came from.
I happen to be listening to the Blackstone Audiobooks production right now.
I’m amused that the Brit reading it (Christopher Hurt) pronounces ‘ULLA’ as ‘allah’.
That stuff around an ice cube is called scotch.
So all this atmosphere we are talking about came
from the frozen solid nucleus? It was originally
much larger and made up of solidified gas that is
now difusing into space, and much faster as it
nears the sun?
Be interesting to see the photos.
Yes. At sea level 1 cubic mile of ice makes 1700 cubic miles of water vapor. Multiply that volume by a bunch to get how many cubic miles of near-vacuum vapor that equals!
I think it's a little more than 'remarkable'. I don't think we actually have a good scientific explanation.
