Just came in from observing and ran DeTeCt on my raw files. Found this on my first run with red. Checked the video and it looks awfully like an impact flash.









Currently uploading to YT. Will add link soon.

EDIT: Here's a link to AstroBin instead. I forgot YouTube will not take SERs.

Wow, good catch!

Very nice capture. An impact seems like a probable cause:

• It has an Airy disk around it indicates it's in front of the aperture.
• It tracks a particular location on the planet, indicating it's local to the planet.

Not sure what else it could be, unless it's a corner reflector on one of those JPL jobs in orbit around Jupiter…

Email it to NASA and /Sky & Telescope/.  You might be famous by morning press.

 

I think AAVSO has a supernova reporting hotline.  They might be able to help put you in touch with the right people for verification.

Can you provide more information on what software you used to detect the flash?  What is "DeTeCt?"

I caught the impact 10 or 12 years ago of Anthony "Bird" Wesley's impact that he was first report. I was sitting at my computer when he sent out the first images going "Uh, what's this" and I still have images that I took of the impact scar. I'd be happy to post them if no one has ever seen one.  I'd say its more than likely an impact. Bird's strike happened on the night time side and by the time it rotated into view there was already a black scar. People that can should image if you don't have clouds, regardless of seeing conditions to see if it was substantial enough to leave a scar. I do believe its rotating out of view in that image? If it left a scar, it's important, but it might not have been big enough.

Without doubt put out word that you were the first to report it, provided you are. I've seen nothing on any other lists. But document it in an e-mail sent to Bob Britt or another science write at Astronomy.com or Livescience.com. If it was big enough to leave a scar, they'll be moving the Hubble to image it and it could take weeks for it to disappear. I wouldn't get my hopes up too much that it was big enough to leave a scar but who knows! Seriously, put out word, I had people who I shall not name, or hell, I'll name him "Dr. Clay" of Arkansas Sky Observatory that tried to take credit for a discovery on Mars that I was first to report and image. I had proof and the reporter actually changed the story on the newswires and I properly got credit. I'm not bragging, but I am proud of it.

...I hope you caught something there Ethan - it certainly looks like it!!!

 

The live feed (I presume) displays an enormously bright "flash" - & if you have more captures (you said it was the first) then as Jupiter rotates one might reasonably expect to see some sort of impact footprint as it comes further into view. 

 

Looking forward to hearing about any possible developments &/or other confirmations...no chance for us of anything with all the clouds & rain we're having!

 

Please keep us posted!

I only mentioned /Sky & Telescope/ because they have a partnership with the AAVSO for reporting astronomical events (S&T helps to run the AAVSO hotline).  No disrespect intended to /Astronomy/ magazine :-o .

The next GRS transit is in ~2 hours; it looks like the flash was on the terminator an hour past transit. I'll move my setup so I can see it; it'll be down around 50˚ elevation for me, but Perth is better situated for a capture. Hopefully Luke (Vega700) logs in and sees this…

Of course!

[Lunatiki]

If it is an impact, contact Dr. Tony Phillips at Spaceweather.com. I'd go ahead and send him what you got saying it looks like an impact on Jupiter. I'd love to see the finished product.

[Tapio]

Not the first time you used DeTeCt ? If so then lucky man.

[DMach]

Nice one, congrats Ethan!

Félicitations Ethan 

 

 

Bravo pour cette découverte c’est formidable

It would be also the first impact detected only by DeTeCt. Marc is going to be happy!

Congratulations Ethan if this is confirmed

The video is completely convicing with a brightening and fading clearly visible.

[GeorgeInDallas]

HI,

 

Congratulations, this looks very similar to the impact that I captured in 2012. I would suggest that you contact Dr. Mike Wong. In 2012 he was running a study that had the authority to pre-empt the Hubble schedule to image transient events on Jupiter. He may want to check for scars on the next rotation.

 

P.S. I was imaging Jupiter and Saturn last evening also. I lost Jupiter behind a tree at 10 PM and switched to Saturn. I just missed the impact apparently.

 

Good Luck,

George

Hi Ethan, all,

 

Sincere congratulations Ethan, I would say that this is a "probable" impact looking at your original data, but it is really convincing, all we need is a second simultaneous observation to confirm it and say it is.

So anyone I urge everyone who observed Jupiter around 04:07:30UT on Wednesday Aug. 7th to look at his data and/or run DeTeCt on it, and if anything is suspect please contact us/me (delcroix point marc at free point fr). Also if you observed it in blue it would be great as we could recover a proper estimation of the energy dissipated (according to Ricardo Hueso).

 

This is then probably the 6th flash discovered by amateurs, the second one in US. Makes the international match even: US 2, Europe 2, Asia/Pacific 2. If you want to make your team win, don't hesitate to use the software (and send me the logs ).

 

Planning for monitoring if an scar was left, it's better to observe in methane absorption band:

Hi Georges, Mike Wong is already informed.

A Jovian supernova? Oh wait...spotting the rotating supernova through Jupiter (facepalm).

Well, my little "claim to fame" (if only on CN) is contained and linked within my sig.

[BQ Octantis]

Just watched the next GRS transit with good seeing at 300x through broken clouds…nothing yet off the terminator. Hopefully the clouds stay this way for the next hour (fingers crossed!)…
