Can you explain what that is in 2342 ?

No, I don't think there is as much data as usual on this comet. I think there must be more periodical comets with much shorter orbit which scientists must have much more time to study in detail. (Someone correct me if I'm wrong guys!). This research can then be applied to other comets, such as expected levels of brightness of a sungrazer comet, composition of the tail etc.

Looks like the remenants of a CME. It's been snapped at a point where the source has disappeared. I've seen weirder ones:

Thanks !

Hey, no problem. Just tell you the way I see it. A few days ago I didn't even know what a CME was! [img]/phpBB/images/smiles/icon_biggrin.gif[/img] If anyone sees a mistake I've made, please point it out because I'm quite a n00b at this stuff.

Actually, I think it's artificial. To quote the BA (from http://www.badastronomy.com/bad/misc/planetx/soho.html ):

Actually dude, looking at that picture a little closer, as well as the preceeding slides, I have to say I don't know what that swirl is! Can anyone clear it up?

So what is a CME? I am the super noob here

It's actually caused be over exposer, the light is bleeding from pixel to pixel. It happens when there is a very bright object.

damn wrong page I was responding to the last post on page 2

Coronal Mass Ejection, I believe.

Yup, I seem to think that's what it stands for too. Hey, talking of conspiracy theorists, here's a great example of why I dislike them:

According to Spaceweather.com this morning;

It is probably debris from the SOHO spacecraft itself," explains Brekke. "We have seen these things in several hundred images. It happens occasionally when bits of insulating material flake off the solar-facing surface of the vehicle. The strange shape could be explained by debris falling into the telescope. At the beginning of the exposure it is in front of the telescope and almost in focus (lower right). Then it falls towards the mirror and grows to a total blur."

Ah, explains a lot. And to think I originally thought it was a CME!!! [img]/phpBB/images/smiles/icon_biggrin.gif[/img]

Let's compare size with Comet V1, and 4 other planets, ie: Venus, Mercury, Jepiter, and Saturn.

If you were to fully examine V1 size, using these planets as a marker point, maybe then we can estimate comet V1 true size?

See & study this image from soho of the year 2000.

http://soho.nascom.nasa.gov/hotshots...lasco_c3v3.jpg


As I remember Soho spacecraft is station/parked @ 1 million miles from Earth.

The Sun is @ 92 million miles from Earth.
Planet Mercury is @ 27 million miles from the Sun.
The planet Venus is @ 57 million miles from the Sun.?

Venus is less than 40 million mile from Earth ?

Venus is the almost the same size as Earth.

Now, when So-call comet V1 passed the closes to the Sun 0.09 au (8 million miles from the Sun), BUT Still V1 is Bigger & larger than the Planet Venus.

Now, you see the problem is that people assume V1 was the whole front portion of comet. It wasn't. The front portion (I'll call it the head) was just a cloud surrounding the tiny comet. The cloud was hydrogen, given off as the suns radiation acts with the water in the comet. Before you start making judgements on it's size, you would have to remove the massive hydrogen cloud to see what's at the centre of it all. It's as it makes its approach to the sun that it gets much brighter.

The image, which includes the outgassing and glare of this object is bigger than it's actual core. The Earth would be tens of miles larger in diameter if we inculded it's atmosphere and our atmosphere isn't lit up or expanding like this comet's.

Comet V1 to emerge from the Sun's glare into
the Southwestern skys, ....next week.

Get Ready.

How do you account for the comet being seen in the xray spectrum of light and not in visible light?
How do you account for all the ionized gas being vaporized off the surface of the nucleaus?
Has it occured to you that what you are seing is only due to the gas being burned off at an increased rate due to its proximity of the Sun?

Use some logic and common sense and study SOHO physics and how and what the images are next time.

Here's thhe full movie of Comet V1 & the Sun, it's real COOL to view.

THANK YOU . http://www.spaceweather.com

Welcome Aramus, happy to see you.
The Movie(wait 30sec+ to load up)
enjoy::

Maybe you forgot about our quaint USAF's "promise":
http://groups.yahoo.com/group/RadarMatrix2003/

Well, I didn't know about the USAFs promise, but the date for such progressions in weather technology is 2025. Have we gained 2 decades? No, the Government does not control the weather as much as I'd like to be able to believe that. Image the implications of such a thing: you could create snow storms over Iraq and freeze 'em to death without the public being able to point a finger at you!
