4:00 a.m. – The Sky Opens Like a Flower
September 20 1977, 4:00 a.m. local time. The city of Petrozavodsk, capital of Soviet Karelia on the western shore of Lake Onega, is still asleep. Then the night turns into day.
A massive glowing object rises silently in the northeastern sky. Witnesses describe it as a gigantic jellyfish or starfish, 100–300 metres across, pulsing with brilliant white light at its core and surrounded by a halo of golden-yellow rays that shoot downward like a cosmic shower. It moves slowly westward at low altitude, hovering for 10–20 minutes. The rays pierce windows, illuminate streets, and cast shadows as if it were noon. Streetlights flicker. Dogs howl. People wake up thinking the sun has risen early.
The object is seen from Leningrad (St. Petersburg) to Murmansk, from Helsinki to Copenhagen – an area the size of Western Europe. Thousands of eyewitnesses, including pilots, sailors, policemen, and astronomers. TASS news agency breaks the story the same day with the headline “A Strange Natural Phenomenon Over Karelia.” Pravda and Izvestia follow. Even Finnish and Swedish papers report it. For once, the Soviet press isn’t hiding anything – they’re screaming it from the rooftops.
The Jellyfish That Rained Light
Key eyewitness accounts (from the official 1978 Soviet Academy of Sciences report):
- Captain Boris Sokolov (Aeroflot pilot): “It looked like a huge starfish with rays extending hundreds of metres. It hovered motionless, then moved west.”
- Petrozavodsk ambulance driver Valentina G. : “The rays were like searchlights but soft, golden. They moved independently, scanning the ground.”
- Meteorological station chief: “The object was at 5–7 km altitude, size comparable to the Moon, but brighter.”
- Multiple reports of “pulsating core” and “tentacle-like beams” that left glowing trails.
No sound, no sonic boom, no radar contact (or so they claimed). Duration: 10–20 minutes before it faded or shot upward.
The Official Soviet Investigation
The USSR couldn’t ignore this one. The Academy of Sciences formed a special commission headed by Dr. Lev Gindilis and UFO researcher Felix Zigel. They collected 300+ written testimonies, photographs, and radar logs. The 1978 report (declassified in the 1990s) concluded:
“The phenomenon cannot be explained by known natural or technical causes. It exhibited intelligent behaviour and controlled behaviour.”
Even the KGB got involved. Declassified files later revealed orders to “monitor public reaction” and suppress panic.
The “Official” Explanation That Nobody Believed
Two days later, Soviet authorities blamed the Kosmos-955 satellite launch from Plesetsk Cosmodrome at 4:01 a.m. The rocket’s exhaust plume in the upper atmosphere, they said, created the light show. Western scientists mostly agreed: a rare “space jellyfish” effect from rocket fuel.
But the problems with that explanation are massive:
- The launch was at 4:01 a.m.; the jellyfish appeared at 4:00 a.m. and lasted far longer than any rocket plume.
- No rocket plume moves slowly westward for 20 minutes or shoots independent rays.
- Plesetsk is 800 km away – too far for such detail.
- Multiple independent observatories (including in Finland) recorded no rocket activity at that exact time.
Felix Zigel called the rocket explanation “laughable” in private letters.

Final Verdict
THE LARGEST MASS UFO SIGHTING OF THE COLD WAR. A glowing jellyfish the size of fifty suns hung over the Soviet Union for twenty minutes, raining golden light on sleeping cities. The Academy of Sciences called it intelligent. The newspapers called it an invasion. The military called it a rocket and hoped everyone would forget. They didn’t. Forty-eight years later, the Petrozavodsk still glows in the sky of memory. Whatever it was, it wanted to be seen.
