The video in the thread was shown tonight on National News.

Magnificent.

On an HD TV it was very clear that this was done by an amateur instrument.

The actual flash was too small to resolve, so the video showed it as an Airy Disk with broken diffraction rings

The diffraction ring scintillated exactly as you would see a star do because of seeing.

Fantastic video. I was not surprised at all to see that it was done by someone known to us...

Congratulations on your discovery, Dan!

It's for events like this that we need a "popthecork" graemlin. You also received some excellent press on the National Geographic website.

However, on a more somber note, I regret to inform the CN community that under the IAU criteria a planet "must have cleared its orbit". As a consequence of your observation and Mr. Hall's video capture of the event, the IAU is convening an emergency session to downgrade Jupiter to "dwarf planet" status. A vociferous minority of planetary scientists, however, insist that this impact was the last little bit of debris that Jupiter needed to capture in order to clear its orbit, and they pinky-swear that there won't be another.

Kidding aside, GREAT WORK!

Regards,

Jim

Yeah, the Earth hasn't cleared its orbit either, it gets hit by meteors all the time ;-)

Great observation!!!

So this is the only video/photo of the event?

You mean to tell me there is no project to monitor Jupiter every second it is visible from somewhere on earth. That it's sad.

Sad maybe...but extremely expensive. That's why we amateurs are out here.

How would an "impact" show as an out of focus Airey disc pattern in bad seeing on an 'in-focus shot of Jupiter ?

I'm standing up and calling foul on this video , prove me wrong please , but it's yet another sad Photoshop attention seeker.

I'm not saying something was not observed but this sure ain't footage of it ! Watch it frame by frame !

Steve.

NASA is very quiet about the event. That made me wonder.

Unlike 2009 and 2010.

I would not call this foul, but I will wait for further evidence.

??Seriously??

You can clearly see the impact flash is actually very much IN focus, and distorted as you would expect from less than perfect seeing ( http://www.damianpeach.com/pickering.htm , I would say the seeing is about 5-6/10). Looks exactly like the 2010 impact as recorded by both Chris Go and Anthony Wesley.

You are wrong. And I'm calling you the attention seeker

Don't belittle the video just because you don't understand it. The video shows a fireball caused by an object far too small to resolve by a telescope from earth (probably <100m and likely in the 10m class of objects.) From this distance, the light flare from the fireball is a point-source that shows an airy pattern through a telescope.

I've viewed the video a number of times and it's completely consistent with the videos of fireballs on Jupiter shot by Christopher Go and Anthony Wesley (independently, but simultaneously) in 2010. In Chris', Bird's, and George's video, the airy pattern of an in-focus point-source of light is shown near Jupiter's limb with the expected light curve (brightening and fading). There's nothing fishy or suspicious about the video whatsoever.

As I said " prove me wrong" . It just doesn't look right to me however many times I watch it. .

Great piece of software by the way.

No, prove you are right. Other than the two exclamation marks you provided I can find no reason to doubt this video. Wayne clearly explained what the video is showing.

OK , Apologies all round , having had a swift firm but polite education on Pickering http://www.damianpeach.com/pickering.htm
I now see that it is a perfectly good shot , I'm sorry for jumping in feet first but it just didn't look right somehow.

Large portion of Humble Pie on order.

Yours put firmly in his place ..

Steve.

Hi Steve:

I have been a planetary observer for nearly 40 years and am a perfectionist. I witnessed this event first hand through a very high quality telescope ($4,000) and at a power of 400 times with near perfect seeing conditions and I'm saying that the fireball I saw did not seem to occur where this video indicates, the explosion I saw did not occur inside Jupiter's Equatorial Zone and it was not that close to Jupiter's morning limb, as I recall. I have gone through my notes from Monday morning and this simulated attachment (shown below) is as accurate as I am able to get as to where ground zero was for this impact event. This explosion did not show an airy disc through my telescope. I think that there could have been two impacts. I'm just trying to understand why our impact locations don't match up. I apologize to George for thinking that his video may be inaccurate, odds are far greater that a visual observation will be off slightly.

Best Regards and Clear Skies, Dan Petersen

Hi,

Here is a photo of my September 10th observing setup, it includes my Orion binoviewer fitted with two Meade series 4000 zoom eyepieces, this is what I looked through to obtain the high resolution and high contrast view of Jupiter. The photo was taken this morning after I rolled away my movable observatory.

Cheers, Dan Petersen

Okay, I'll retract my kudos to the video's creator and limit them to Dan for now!

I was wondering about the video, too. Clearly an explosion wouldn't be in the shape of Mickey Mouse like that. (Zoom it.)

Regards,

Jim
