Soviet Petrozavodsk Jellyfish Phenomenon 1977

In the predawn hours of September 20, 1977, a massive luminous jellyfish-shaped phenomenon appeared over Petrozavodsk, the capital of the Karelian ASSR. Witnesses reported an enormous glowing object that hovered over the city emitting thin beams of light that struck windows, leaving circular perforations in the glass. The phenomenon was simultaneously observed by Finnish air traffic controllers across the border. In an extraordinary departure from standard Soviet secrecy, the TASS state news agency published a report on the incident — the only UAP event to receive official Soviet media acknowledgment in the Cold War era. The Soviet Academy of Sciences subsequently investigated, interviewing hundreds of witnesses. US intelligence noted the TASS report with interest. The window perforations were physically documented and measured. The event is considered the most significant officially-acknowledged UAP incident in Soviet history.
