Could Vanishing Stars Be Alien Satellites Or Is This a Cold War Relic?

Your explanations don't take into account the fact, as reported in the Villarroel-led study, that the transients don't appear when the upper atmosphere was shrouded in the shadow of the Earth. If the transients were the result of imperfections in the plates or nuclear test fallout, shouldn't they have been equally represented in images obtained during all phases of night? Furthermore, the incidence of transients is not positively correlated with nuclear test times and dates.

I live in Southern Ontario, Canada. I was born in 1950. When I was five, an announcement over the radio stated that we wern't able to drink milk as a nuclear test had been conducted with the fallout coming toward us. The cows would eat the grass with Strontium 90 contamination. So there was a two week period of no milk.

It's fascinating what the comment section becomes when aliens are mentioned

Hello, wonderful person! This is a two part series with the part 1 of the video here: https://www.youtube.com/watch?v=5_Pw_rY04sI This is the part where the Earth shadow disappearance is addressed too Also another study confirming that this was a result of photographic paper packaging: https://journals.aps.org/pr/abstract/10.1103/PhysRev.76.375

That is why dark plates are important for calibration. Basically test exposure of nothing. So just developed of unexposed plates. While patter of dots will be different it can give idea of statistics and development process issues. With electronic sensors it is even more important as some pixels will persistently by bad so dark frames are more useful. But still useful in analog astrophotography.

I'd want to focus on objects that show on two plates but go missing on a third. To show it is not contamination spots on a single plate.

I used to live just north of the Palomar observatory. You could see the telescope dome from my back yard. You can go and see the telescope still. There is a lot of history there. Its a pretty cool place.

I bought a Kodak for my dad when I was a kid. Within weeks there was a lawsuit for patent infringements. I was supposed to get a share of stock for the camera. The company sent a document but they never followed up. That's when I knew it was going to be a rough life. Thanks Anton. You are always there for me.

If the plates still physically exist, you could take samples of the gelatine on the surface and at different depths at suspected transient/contamination points and empty space (as a control) and use a GCMS or some other kind of mass spec and look for specific radionucleotides and their specific end products to physically prove the contamination hypothesis. And at this point, it is only a hypothesis, lacking any verifiable evidence.

I have an original Kodak hat as well, it was my late dads he worked with them/at the place a bit from what my moms told me :)
