The Greifswald Lights

The date places this at the very end of the German Democratic Republic, in the weeks before reunification, on a stretch of Baltic coast near the Greifswald nuclear power station. What people on the dunes at Usedom and Ahlbeck described was not a passing light but chains of luminous balls. They hung in the sky and moved slowly up and down without sound for about an hour.

What is on the record

Two tellings on a single channel and four claimant entries, including the named witness Jens Hollatz and groupings recorded as East German military and scientific personnel, Russian military personnel and a large crowd. There are no documents. The grade is testimony.

The strength of this case is that it was filmed, and filmed more than once. The archive's summary records multiple independent videos showing the same cluster of objects, taken by observers described as qualified. That is a materially different situation from a single camera, and it is what has kept Greifswald in discussion.

The standing explanation is military flares, and the record engages with it rather than dismissing it. The counterargument held here is duration: the lights are described as hanging for roughly an hour, which researchers in the telling argue is inconsistent with flares. The archive does not adjudicate that, and no film is in our holdings for us to examine.

The setting is worth noting without overclaiming. Our spatial study finds reports enriched near nuclear weapons sites specifically, at 4.27 times chance within 25 kilometres, while civil reactors show only a weak effect. Greifswald was a power station, which places this case in the weaker category rather than the strong one.

Why it sits where it does

L3, on multiple claimants and repeated filming, all reaching the archive through one channel. What hung over the Baltic coast that evening is not resolved here.
