The Greifswald Lights historically-pivotal-explained
On the evening of 24 August 1990, dozens of witnesses around Greifswald Bay in
the still-Soviet-occupied former East Germany — within sight of the Lubmin
nuclear power station — saw a formation of about seven glowing yellow-orange
lights hanging and slowly fading over the Baltic, captured on several amateur
videos and, after a four-year investigation, attributed to parachute
illumination flares from the last major Warsaw Pact military exercise before
German reunification.
A genuinely mass-witnessed, multi-video nocturnal-lights case from the former
East Germany — repeatedly called 'the best-documented UFO sighting in Germany' —
that has nonetheless been credibly resolved as routine military activity near a
sensitive nuclear/strategic zone. It adds German/Cold-War geographic breadth
and a clean 'military exercise misidentified as a UFO formation' exemplar,
pairing with the Canary Islands (submarine-launched missile) and Ladakh
(planets/lanterns) as explained mass-light cases — illustrating how flares plus
heightened expectation produce a 'controlled formation' impression.
Timeline
1990-08-24_2000
Around 8-9 pm, roughly 50 coastal residents plus West German tourists between
Greifswald, Rugen, Usedom, and the Rostock coast report ~seven reddish/
yellow-white luminous spheres arranged 'like a bunch of grapes' (also V- or
Y-shaped), moving slowly and soundlessly with slight internal shifts, weeks
before reunification in still-Soviet-controlled territory near the Lubmin
nuclear plant.
witnesses: ~50 coastal witnesses (incl. the Iwanowa couple, interpreter Waleri Winogradow)
primary source: GWUP Skeptiker 4/1999; CENAP
1990-08-24_video
Multiple amateur videos are made (commonly cited as six); a ferry/boat
captain, Erwin Kollath, recognizes the lights as 'Leuchtbomben' (illumination
bombs). Total observation across sequential events spans ~30-45 minutes.
witnesses: Erwin Kollath (ferry captain)
primary source: CENAP; MUFON-CES
1990-1999
Werner Walter / CENAP conduct a four-year investigation, later endorsed by
GWUP (Skeptiker 4/1999): the lights were parachute illumination flares fired
by small rockets from warships during a Warsaw Pact maneuver in the Baltic
'Luftschiesszone II,' with sequential launches explaining the duration. Named
NVA/defense sources (Dr. Luder Stock; Franz-Lorenz Lill) support the reading.

Named personnel
- Werner Walter / CENAP — German skeptical investigators who ran the four-year inquiry attributing the lights to military flares rank at time: role: the prosaic resolution
- Erwin Kollath — Ferry/boat captain on the night who recognized the lights as illumination flares ('Leuchtbomben') rank at time: primary witness to: the flares, identified on the spot
- Dr. Luder Stock & Franz-Lorenz Lill — Former NVA officer and GDR Air Force spokesman who described ship-fired parachute illumination flares / signal bombs rank at time: role: the military corroboration
- Michael Hesemann — UFO author who called it 'the best-documented UFO sighting in Germany' (pro-anomaly framing) rank at time: role: the pro-anomaly reading
Object — reported
shape
~seven glowing yellow/orange-to-reddish-white spheres in a loose cluster/formation ('like a bunch of grapes,' also V/Y-shaped)
size
indeterminate; distant lights over the bay, captured on short home videos
surface features
no structure — glowing points that hang, drift slowly, and slowly fade
observed behaviors
- the formation hanging and drifting slowly and silently over the Baltic with slight relative motion, on multiple amateur videos
- on the resolved reading: parachute illumination flares igniting high and descending slowly under oversized parachutes (or hanging in thermal updrafts over the warm Baltic), with sequential launches explaining the ~30-45 minute duration
- a ferry captain on the night recognizing them immediately as illumination bombs
Theories that invoke this case (3)
The mundane luminous-phenomenon reading: parachute illumination flares hanging and slowly fading over the bay — bright lights misperceived as a structured formation.
The military-activity reading: the actual stimulus was a Warsaw Pact / Soviet military exercise firing illumination flares (or missile-practice illumination) over the Baltic range near a strategic site.
The perceptual reading: the 'controlled formation/maneuver' impression that flares plus heightened expectation readily produce, sustaining a 'craft' interpretation despite the mundane cause.
Theories that do NOT invoke this case — and why
an aerial-lights case, not a creature record
the cause is credibly identified as military flares, with named military corroboration
no material trace; the evidence is video of distant lights
Conventional explanations advanced — and their status
Soviet / Warsaw Pact military illumination flares
proponents: Werner Walter / CENAP · GWUP · named NVA/defense sources
The strong, widely-accepted explanation: parachute illumination flares ('Leuchtbomben') fired by small rockets from warships during the last major Warsaw Pact maneuver, descending slowly under parachutes; the only explanation backed by named military witnesses and a ferry captain on the night.
Missile / illumination-target framing
proponents: some accounts
A variant of the same event — whether an actual missile was fired versus ship-fired flare rockets is contested, but the military origin is not.
A controlled craft / genuine UFO
proponents: Michael Hesemann · Johannes von Buttlar
Weak: rests on subjective impressions of formation and maneuver that flares plus expectation produce; the duration objection is answered by sequential launches, and one unreleased MUFON-CES film reportedly showed smoke trails.
Where further investigation has leverage
- The surviving videos and photos (photometric/positional analysis — fade curves and drift consistent with parachute descent versus powered flight).
- Cross-bearing the multiple vantage points (Greifswald/Rugen/Usedom/Rostock) toward the Baltic firing range to fix range and altitude.
- Soviet/NVA exercise records for 24 August 1990, and recovery of the unreleased MUFON-CES film reportedly showing smoke trails (potentially decisive).
Corpus status
historically-pivotal-explained
The documented core — many witnesses, multiple home videos, a formation of slowly
fading lights over a known Baltic military range, corroborated by named NVA and
defense sources and a ferry captain — converges on parachute illumination flares
from a Warsaw Pact exercise. The 'controlled craft' reading rests on subjective
impressions of formation/maneuver that flares plus expectation readily produce,
and the duration is explained by sequential launches. English-language UFO sites
still label it 'unsolved,' a framing the investigative record does not support.
