Comets Collide with the Sun?

Have a look at this:

At the Start and End dates fields, type: "2009-12-23" and "2010-01-05"

Select LASCO C3 and resolution 1024 (512 may give better play back). Search and let the browser load in all the 500 or so frames. Then play and click "Faster speed" 3-4 times to get a smooth play back.

There are two small comets (entering Dec 27th and 29th) approaching the Sun before the obvious one entering Jan 1st.

Now, there is a 4th object I'm wondering about. From Jan 1 st, check the bright planet-like object traveling horizontally from the left and rightwards, above the vertical middle. It has a clear linear perspective as it travels (almost disappearing passing the middle of the image), and can't be orbiting the Sun like the planets, nor as a comet.

What the heck is this?

Probably Venus or Mercury.

Hm, yeah, but I'm not referring to the planet that appears slowly across the screen. This object goes relatively fast, and apparently above the ecliptic plane (depends on SOHO's point of view and movement). The object's movement seems quite linear and also with a clear perspective inwards in space. If it was orbiting the Sun like one of the planets, wouldn't one see some curving in its path, and for sure, moving slower? Also, it has the bright side towards us, so with this alignment and apparent movement, it doesn't make much sense as a planet (?).

See illustration:

Comets colliding with the Sun, it seems reasonable that this would happen on occasion, no?
If [url2=http://www2.jpl.nasa.gov/sl9/]Shoemaker-Levy 9[/url2] could collide with Jupiter, then why not with the the much larger Sun?
That brings up another question- are there any observations of the comet fragmenting, as did SL-9?

However if NASA has spectral data on the composition of the comets coma as being mostly water ice and dust, that would be pretty strong evidence against EU.

Not really, bro. It might seem to validate the 'snowball' hypothesis, but the thing about the EU hypothesis doesn't preclude that a comet could be an iceball, or a ball of sandstone, iron, or any other planetary matter!

However, I think the idea that a dirty snowball could pass anywhere near the Sun and not go Pffft! into gas from the heat is ludicrous.

Especially with the sungrazers- I doubt that they are anything other than very, very solid material to withstand the heat of proximity to the solar body.

Think maybe that was another of the orbital solar observatory satellites. Isn't SOHO one of a team of four satellites? And aren't there multiple research platforms now in position for solar observation now?

If Venus was on the near side of the Sun it would move about this much in 3 days. The slow one will be a planet on far side of Sun.

If Venus was on the near side of the Sun it would move about this much in 3 days. The slow one will be a planet on far side of Sun.

The object travels in the opposite direction of the slow planets' orbit; i.e. as if on the near side. But why does it then disappear inwards while traveling across the field of view? Being on the near side of the Sun doesn't make too much sense either, as it is illuminated as on the far side (more or less like a full moon). If on the near side, little of its lit surface would have been seen.

It appears like a bypassing radiant object, a comet without tail or an object traveling at extraordinary speed at the far side of the Sun (or at a chord path across the ecliptic plane). I would normally assume it as a planet, but as I've pointed out, the apparent movements doesn't (so far) account for it.

Comet Halley's Nucleus: An Orbiting Iceberg.

Ok so NASA says. But is there any spectral data or composition info of the comets tail? What is the comets tail composition? What percentage is water ice?

If any one has info please post! If EU is correct, that picture could be of EDM discharge on the surface of the comet! Plasma around the comet?

To be fair, here is one that didn't do anything, it just short of faded away.

It has been pointed out on several occasions that the hydroxyl creation in the comet comas and tails is often referred to as 'water' by Mainstreamists.

Best summary article on comets in the TPOD section is this one (thanks Stephen!):

http://www.thunderbolts.info/tpod/2009/ ... aments.htm

Forget the water... there's lots more stuff that EU explains that the Mainstream model can't! How does the amino acid glycine form on a cold 'iceberg'? EU can explain how it could be found on a comet tho...:

That comet may have triggered a CME after all.

this would be 16:09 UTC

I'm betting on a weak CME occurring in about 36 hours.

I think it was closer to 40.

Note in this video that there is a subtle brightening to the lower left after the comet passes that area when the timestamp reads 2010/01/03 19:54

In a more recent video there is a CME in the same location, which is already underway at 2010/01/05 18:54

On the SOHO "theater", selecting Lasco C2 with start date of 2010-01-04 and end date of 2010-01-06, there is an obvious brightening in the corona in the upper left of the image starting around 2010/01/05 10:30 and continues to get brighter until the CME burst at 18:30

Anyways, considering how quiet the sun has been with few CME's, this seems more than a mere coinkidink.

Influx,

No, that does not have to follow........if the comet is mostly water and ice it would have a very high ratio of energy per unit of mass, in relation to an underlying force of energy affecting the form and function of physical structure.

The universe is still electrical, the only difference being that the electrical factor or portion of universe is itself a dynamic response to the underlying force as is gravity.

We might also consider the core of the sun consisting of ice in the form of frozen gas, due to the highly energized state of the core.

I remember a series of x-ray flares as the comet was approaching the sun.



Could that be a signature of the comet influencing solar activity?
Mental note: check x-ray flares during the next sungrazer.

I have noticed these flares before. They frequently occur at intervals of ~160 minutes (or 9 per day). That period is a solar oscillation period and also associated with a standing wave that fits the outer planets. Light takes 160 minutes to travel from the Sun to Saturn and back, and twice that to Uranus, 3 times to Neptune and 4 times to Pluto (also 1/2 that to Jupiter).

Also, something in orbit just above the Sun's surface would take just over 160 minutes to orbit the Sun. So any gravitational disturbance of the solar surface is likely to travel around the Sun in that time. This would likely apply to objects hitting the Sun, but the orbital period of gravitational disturbances associated with objects away from the surface would be much longer.

[solrey]

I see some similarities to a ion discharge wave. A slight rise, then a drop preceding the discharge that "relaxes" over several "strokes".



I'm not seeing any consistent 160 minute periodicity in that x-ray signature there, skip.
(skip, as in a broken record)
