Witnesses across northern Europe — from Karelia to Finland and Sweden — reported a luminous, jellyfish-like object that hovered over Petrozavodsk for ten to twelve minutes. The Soviet Academy of Sciences opened a dedicated scientific study (Setka-AN) and a parallel Ministry of Defence programme (Setka-MO) in direct response. The most likely conventional explanation — the launch of Kosmos 955 from Plesetsk — does not fully account for the duration or the witness geography.
