Hi Steve

I just wrote a response, that I hope you didn't catch in the five seconds it was up, before I deleted it. I completely misunderstood your last message and thought, for some reason, that you firmly stood on your opinion that the video was false. I am sorry if I caused confusion to anyone.


Clear skies!

What do we think about THAT comment from Dan Peterson...

FrenchStar,
That long URL you posted has suddenly made reading on my small-screen device a pain. Would you kindly edit your post so as to make a shorter link? Thanks!


All,
The title of this thread, as well as at least one other news headline, had me chuckling, with images in my head of flaming balls of fire hurtling through space!

Nice catch! Would love to witness something like that. Too bad no scars left behind.

The airy disk doesn't look out of focus to me, though it is rippled by the seeing. I can get a glimpse of the airy disk and fragments of first and second ring, essentially perfect performance from a 12" SCT in that kind of seeing, in my experience. Size relative to Jupiter also seems spot on.

Clear skies!

And that it does show an airy disk can be seen as a measure to a degree of how large the fireball is not.

By the way, was looking on the morning of the 11th, and saw an anomalous white spot near the limb in the right location. Hadn't heard the news.

On the 12th, spotted a diagonal black mark near the center - looked like a scratch on a disc of plastic by an Xacto. It was the diagonal nature of the artifact that drew my eye.

On the 13th, fogged out.

Weather permitting, I'm almost always observing Jupiter every morning - the two above anomalies stand out beyond the shifting patterns in Jupiter's bands, plus of course Oval BA, Red spot (compression wave ahead, turbulence/knots behind), occasional festoons, and ... when very stable, small while spots in the bands.

I think there was a small artifact. I'm hoping to see if there's another chance to find it, assuming it persists.

But not on the scale of earlier impacts, or of similar shape.

Still looking

On 14th, very small dark spot in right place but very poor conditions looking through sucker hole and poor seeing - no confirmation, as could have been part of a starting/small festoon.

A blogger on the Starry Nights Yahoo group said he saw a string of black spots along the Northern Equatorial Band on the morning of the 14th. I think this was probably just a string of barges, since the description and location fits. Barges often look like a string of black pearls. Best to check with recent photos of the area. That is what I told him.

The visual discoverer's post in the planetary imaging and processing forum should have been moved here by the moderators... Has anybody here been following the ALPO Jupiter yahoo group? I wonder how the observation is being discussed there - how their discussion could be summarized from the visual observational perspective.

EDIT: I have read up on the topic on the ALPO forum but found that the CN thread in question contained the most visual observational details by far. Thankfully that thread lives on, albeit on the image processing forum.

IVM,

I'm not a member of the Yahoo Jupiter group, but I am a member of A.L.P.O. and I haven't seen any posts anywhere else on the Web that confirm a visual sighting or image of any residual scar from the fireball strike (except for one post referred to above which I believe was mistaken).

It appears that this strike was from an object so small that no impact scar was resolvable from Earth-based optics--much like the last strike documented by imagers.

This in no way detracts from the original visual observation confirmed by independent imagery. Congratulations to those folks.

Jupiter just needs to be hit by bigger stuff so the rest of us can watch the aftermath (or maybe if we're really dedicated and lucky see the actual strike).

Is it not reasonable to expect that by now some of the world's most capable professional observatories would have turned some of the world's most powerful telescopes on Jupiter to look for some evidence of this strike?

I think they're more interested in planets around other stars.

The fireball area was imaged in IR by Glen Orton in Hawaii and nothing unusual was seen.

Indeed the black scar in 2009 was so huge and "unnaturally" colored that I "discovered" it in our typically poor seeing before reading about the impact. I clearly remember the uncontrolled kind of feeling of worry that I experienced when seeing that feature. Obviously that was the time when impacts and scars were not on everybody's mind like they are now that we seem to be having a string of observed impacts in the recent years. The story also illustrates of course that I am always way behind the pack as far as Jupiter. Eagerly awaiting more details about this time's observations,

The discussed absence of the "scar" in no way detracts from either observation (visual and video), I agree. But we should not glance over important details and forget that neither observation is a confirmation of the other. The flash in the video is close to the limb in the EZ. The visually observed flash was farther from the limb in the NEB. I think the visual discoverer (Dan Petersen) has made this point very clear in the Planetary Imaging forum thread here on CN. It is important to point out that the video observer (George Hall) unearthed his Jupiter footage with the flash after Christopher Go published on the ALPO Jupiter forum Petersen's private email to him that contained the coordinates and that was additionally specifically saying it was in the NEB.

So it would seem that, to borrow the expression used on the ALPO forum, even "in the court of law" one could logically exclude the likelihood of conspiracy. (I personally shudder to even give consideration to such ideas... but since I hear they are out on the internet I can as well present hard evidence against them.) Conspiracy would aim for consistency and at least absence of obvious contradictions between the visual and video observations. Here we have, however, an obvious contradiction. If Mr. Hall (again, it is revolting for me even to write something like this hypothetically) wanted to fake the video, he would photoshop the flash where Chris Go's post said it was seen, wouldn't he?

I think the community will do well to accept that although in general it is not easy to pinpoint the location of a brief flash visually, in this specific case this has been done with certainty, as described repeatedly by the observer. So there is no conspiracy, but nor is there a confirmation.

Well, both the visual observer and the imager independently reported the flash at 1135 UT. Although the observer insists that the location of the strike he saw is different from that recorded by the imager, the flash was very brief and left no residual mark. In spite of that, he reported the location very close to where it was recorded by imagery. It is understandable if he got it a little off.
