It's not showing up anywhere. So much for the "Comet of the Century..." :bawling:

Maybe it'll come back as a zombie comet...

IDK, this guy shows a pic of it making it:
Comet ISON made it!

Initially the dust stream will be reasonably compact, but will diffuse due to acceleration effects and separation my mass in the solar wind. The dust will continue on out of the solar system.

I'm not sure I'd count it dead yet. The latest SOHO C3 image appears to show the head brightening again as it is leaving.

Is that Saturn in the lower left of the SOHO image?

No, I believe that is Antares. You can see M4 as a faint blur to the right of it. The thing that looks like rings on it is just " blooming" due to saturation of the CCD pixels.

Thanx. It looked odd with such a thin "ring".

Per Phil Plait @ Bad Astronomy...

"That looks like debris to me, or at best a very small and pale reflection of the splendor of what ISON was."

I guess we'll just wait and see. Something is better than nothing, and nothing is what everyone monitoring the approach with images from the Solar Dynamics Observatory Spacecraft said we were left with. All the SDO images of the approach, perihelion, and departure of Comet ISON showed NO comet at all.

Using the NASA SOHO movie player...

http://sohodata.nasc...o_movie_theater

...you can load up the last 130 LASCO C3 images, and then as you watch the loaded movie you can see the head of ISON become smaller and dimmer in the last few frames of the approach. So it seems that it must have either broken or burned up such that what we see coming out from the blocked disc of the Sun is rather small in comparison to the much larger comet we watched approaching the Sun in those first few frames...

Seems a little anti climatic after a billion year journey.

Well, I think it actually might have been very climactic for the comet! ;)

Edit: According to the latest SOHO images linked above, ISON is still with us. Time will tell...

Just shows what fickle, unpredictable things comets can be

Here's a link to the SOHO LASCO C2 movie that shows the comet's death and then what's left of it clinging to life as it comes out from behind the sun...

Although it takes about a minute or two to load on my computer, I still prefer the LASCO C3 movie I linked to 7 posts up from here. However, you should load the last 180 images rather than 130, and you will get more of the movie with more detail, including the reforming of the new tail. Hopefully what we now see here is just a smaller comet that we can still see in our binoculars and telescopes next week...

Hope is good... :jump:

Yeah, the latest LASCO C3 movie frames are promising...

Now that a few more frames have been loaded, I have to say that promise is turning to pessimism for me. It almost "fades to blue" there at the end. It's true that I don't really know how to translate the LASCO C3 image to the same image behind an eyepiece of a binocular or telescope, but after watching the image fade so quickly after leaving the Sun, it's hard to get too excited about what the near future holds for it... :confused:

After such an involved discussion about the life or death of Comet ISON, it looks like the thread title was correct after all... Comet ISON dies as it rounds the Sun... :(

I know it's just a 4.5 billion year old snow ball, but I am as sad as I was when my big friendly snow man melted in the rain when I was a kid. Very sad that it died. Mean old Sun.

As Miracle Max once so famously observed - maybe it's only mostly dead..... :grin:

What about Lovejoy...no media coverage and I was out this morning at 5 AM and it was visible easily naked eye from my location.

Great view with long tail using Fuji 10x50s.

:cool:
