He says: But to explore all avenues, it is worth looking into "If it WAS am object, what properties would it have to have had?" I assume this is derived from properties of the camera/lens?

It wasn't. Villarroel's own data with regard to plate edges strongly suggest that the flaws/"transients" are more dense near the plate edges, though depending on the algorithm, this may be exacerbated by plate overlap. Remember, the graphs of the...

The width of the reporting corridor relates somewhat to the altitude of the lights. A higher altitude would be visible from farther off. The map would profit from a scale, both distance and time (since the length of the lines is proportional to...

While I have complete respect for your research skills, I think we need to be careful with this data. Any report made more than a year, if not a couple of months, is likely tainted. By that time the media coverage was already creating the...

Some of the estimated UFO flightpaths are very near to/ overfly Phoenix Sky Harbor International Airport. If an unidentified aircraft with bright lights were involved, and it was present for 15 or more minutes over Phoenix, some of the time very...

I kinda wanted to disagree cos I don't think it's a leading question. But then presumably a question is not the same as a prompt. Would that be correct? Forgive my ignorance on asking prompting AI. I did note the "Yes" didn't really match the...

Exactly. I think it might be an artifact in the film, but if was impossible to recreate it too, it would be closer to a debunk. But it's actually possible for it to be an object, that's all I tried to prove. Yes I made the Blender camera with...

Right, in those days no one even used the term "Schmidt telescope". The focal plane is not accessible from the outside. The Hamburg camera is almost an identical copy of the Palomar Oschin Schmidt camera.

They *are* routinely detected by large survey telescopes, to this day. And automatically thrown out as space junk. That's why it is important (from my viewpoint) to study them. If nothing else, they have to be removed so the actual astronomical...

As far as I know, they *are* being detected. They are just throw away by the automatic data processing pipelines, or by the astronomers themselves, as the standard explanation for them is space junk. Modern survey observatories like Rubin and...

Catalog matching was done. That can be tested: three MNRAS 2022 datasets are published here: http://svocats.cab.inta-csic.es/vanish/ Select the list of vanishing objects in POSS I red images (5,399 rows) and perform a cross-match against Gaia and...

I understand the Palomar plates aren't available because of policy issues. They are seen as irreplaceable assets. The Applause plates might be available for physical inspection though.

That suggests that the questions should be about the witnesses rather than the the objects themselves. Don't discount the possibility of "bandwagon" sightings, the urge to be part of the crowd that makes people say "me too, I saw it" when all...
