>Flights of single, group and squadrons of the ships were detected

So they are now calling them literal ships, not ufo or uap

Also, from their methodology and instrumentation (color cameras) it seems they could have done it in like 80s. Why coming out now?

This exactly, seems like this could have been done from the 80s and entirely automated from the mid-90's.

I'm all for setting up something like this [1], it's just good science to have automated cameras recording the sky to keep an eye on things. In the very simplest straightforward business case, three synchronized cameras detecting a meteor can trace its path through the athmosphere and help locate anything that hits the ground. For more niche use cases include tracking aircraft flying around with their transponders turned off, just to keep everyone honest. After a few dozen more scientic use cases, then, maybe, some UFO tracking.

Sky Hub [2] tried it, combining recording with some ML detection, but they went bust last year.

The paper is by three Ukranian astro photogrammetrypeople .. I was going to comment on "ships" for the bias but figured I can mark that down to non native English speakers and some translation issue.

Nothing in the eight pages screams "we believe in aliens", it's essentially about not yet catogorised observed phenomona high up in the troposphere.

With limited data on fast objects that appear in only a few frames they write about two classes of "things".

The earth, of course, sees an infall of roughly 48.5 tons of material per day of various sizes and composition, much of which never reaches the surface directly, instead breaking up and falling as dust.

The phrase “squadron of ships” seems like deliberate word choice. And to me, “squadron” is a more alarming word than “ships,” because it implies cooperation between multiple intelligent entities. But the paper does not describe much compelling evidence for any intelligent “swarming” behavior, so I interpreted the word choice as bias.

The crescent shape looks like it could be side view of the ionized part of a shock wave (maybe there’s a better word for it).

[TechBro8615]

The paper isn’t clear about this, but the crescent in that image is the moon, AFAIU. They’re using it as a baseline for luminosity of the UAPs, which are the multiple (less bright) white speckles in the image.

"moon"?

The 80s were mostly about DSLR cameras with film (whether colour or black and white).

These three are currently focused on what can be determined from CMOS cameras using more recent techniques.

eg:

Meteor colorimetry with CMOS cameras

https://arxiv.org/pdf/2106.07403.pdf

treats digital captures as a limited range spectrogram in the visible spectrum normalises values and attempts to determine estimates for "the characteristics of meteors such as temperature, chemical composition, and others".

As this approach is based upon "new algorithms for estimating temperature, heat radiation emitted by a fireball, and spectra of meteors containing emission lines using a new approach based on colourimetry" it seems they are publishing now as they had neither the cameras nor the algorithm some 40 years ago, and perhaps were not yet born.
