@jimmyslippin suggested this might be a good candidate for Sitrec. One thing I've not yet done in Sitrec is add support for regular illumination of satellites - i.e. large things like Space Stations that are bright simply because they are in sunlight (and then vanishing when they go into the...

Should be fixed. I could not duplicate #2, but it might be a side effect of other things I fixed. If it's still happening, please post the KML and how you make it happen.

Oops! I've been making some significant "improvements" to the code, which invariably have side-effects. I'll fix this ASAP.

The description sounds like it, but the video shows one light at the start that's there for over a minute, which seem too long.

Eliminating modern fakes is a necessary step in making sure you're actually looking at something ancient. There's no point trying to find out how the ancients made something if they didn't make it.

There’s a “custom” sitch where you can drop a video (.ts converted to mp4) and then a KLV file extracted from a .ts. Still a work in progress. Does not load terrain yet. It can also load ADSB tracks and MISB extracted to CSV https://www.metabunk.org/sitrec/?sitch=custom I could do with some...

Keep in mind the Sitrec recreation is based on very low resolution data (Az and El) which does not capture: A) The precise angles the camera - the field of view is about 2° vertically, and Az and El are only accurate to about 1°, which is half the screen. B) The movement of the object in the...

https://www.metabunk.org/sitrec/?sitch=nellis So I chopped it down to just the S-30 portion. Added the radomes exactly where they should be, and the mountain profile is a good match. It's very obvious that the range value is not working, because when the range changes rapidly, the object and...

Source: https://twitter.com/anthroaerospace/status/1785699760021672124 All black but had a greyish tan patch on the top. Saw it at eglin ... This thing was flying way out of florida into the ocean with a c-130 tanker following. Idk where it went ... Its almsot the size of a c-130 so no but i...

I'll try that in a bit. Off for a walk!

Fixed, I think (09:44). I also added a compass. https://www.metabunk.org/sitrec/?sitch=nellis

First pass Sitrec: https://www.metabunk.org/sitrec/?sitch=nellis The location of the camera was suggested by Marik. I'm not sure how accurate it is. There's a new menu option: "Segment" which lets you highlight portions of the track. The first one (0-4404) is a straight line at constant...

Thanks! I shall put it into Sitrec later today. BTW, I've set up Sitrec so anyone can create a sitch. It's somewhat hampered by the lack of documentation, but I'm gradually improving it. https://github.com/MickWest/sitrec/blob/main/docs/CustomSitches.md

Not impossible. I've been working on making it more general purpose, so you can set up your own situations. And of course they might use it for Aguadilla. I'd be surprised though.

You see that in my old simulator: https://contrailscience.com/contrail-simulations/ (uncheck the "Intersection" box in lower left)

Everything not moving in the view (assuming the camera does not rotate) is moving relative to the plane at 352 feet per second, or 11.7 feet per frame. If it were 100 feet long it would move 0.117 times its length (11.7/100) per frame. The distance is irrelevant because things look smaller, as...

It's an assumption to test the question: "is this consistent with a balloon". If it can be shown to be moving under its own power then that would invalidate the balloon hypothesis. But what we can say is that there is nothing inconsistent with it being a balloon.

We don't. We know: 1 - the plane is going 240 mph, or 352 feet per second 2 - the object's apparent speed is about 4.3 times its own length per 1/30th of a second From just those two things, and assuming it's not moving under its own power and there's no significant wind we can estimate the...

There was a thread last month discussing a lower quality version of this video, with less information:https://www.metabunk.org/threads/ufo-filmed-over-new-york-city-what-is-it.13406/ In particular there was discussion about it being a solar balloon. If the calculation of <3 feet is correct, I...
