SDO Views Comet ISON

reply to post by Nootropic


I really don't remember where I read it, that they need to change the lens... for sudden brightening of ISON. in spaceweather.com it says this:

Over the course of the animation, Comet ISON brightens by a factor of at least four, and possibly as much as a factor of 10. It easily outshines the 1st-magnitude red giant star Antares to the lower left of the sun.

has you can see in this graph...

don't know if it helped

Can you believe it, 1 week off from work and nothing to do.......

I'm glued to the computer the next coming days!!

Peace

PS: 1 day, 5 1/2hrs till ISON makes it's appearance on SDO....whoohoooo.

You chose a great week to have off work!! Hope it lives up to everyone's expectations!

This morning it is indeed with a heavy heart that I show you the image opposite, in which we clearly see that ISON has faded rather dramatically in the past few hours. It is still likely around -1 magnitude, but this number is falling fast.

That is discouraging.

Karl Battams is now saying he believes ISON will reach perihelion, but he will be surprised if we see anything emerge from the other side.

Hey, this is just one astronomers opinion--we can still hope!

Well time will tell.

Remember comet lovejoy, it survived perihelion with style.

Here is the most recent image I can find--from almost I hour ago, LASCO C3. Sooo close.

image source

This is from C2 SOHO

That is discouraging indeed....but lets not lose hope!!

30min to go!!

Peace

Not a d@#n thing coming into view.....??

Probably disintegrated or pictures are really taking a long time....

Any news on ISON?

Peace

Leonid Elenin said minutes ago Comet ISON was disintegrated...

That's probably why I'm not seeing anything.

Poor ISON....He never stood a chance.

Thanks for the update!

Peace

They're sayings it's not visible on SDO, didn't catch why but it may not have disintegrated...

Okay, that's weird.

Guess there's nothing else to do but wait. Any word if it will be visible on LASCO after it's swing around the sun?

Peace

reply to post by operation mindcrime


I imagine that if it survives it will show up on LASCO again.

They're just saying that because there doesn't seem to be a bright "dot" that it could indicate it has started to break apart and doesn't have a solid nucleus anymore.

reply to post by operation mindcrime

it should have made perihelion at 18:44 UTC, SDO AIA 0131 is showing images till 18:08 right now... and theres nothing...

See my post at www.abovetopsecret.com...

ISON is visible, as a tiny dot with a very small and faint tail, in SDO images from AIA 193 camera.

"Approach"

"Perihelion"

"Departure"


Here it is in the AIA 171 image:

"Perihelion"


So someone's got to tell those NASA buffs that they can see ISON in SDO images!

After a more careful examination, I came to the conclusion that those are just optical artifacts (maybe cosmic particles). They appear purely at random, at times that don't correspond to the progress of ISON around the Sun. Sorry for the false alarm. ISON was not visible in SDO.
