Montluçon, France: Two women watch yellow hemispherical object with fan-like filaments
From 1:45 to 2:30 a.m. on April 21, 1957, Gilberte Ausserre and Rolande Prevost watched a blindingly bright yellow hemispherical object over Montluçon, Allier, France, that grew to the apparent size of the full moon, vanished and reappeared several times and emitted green and purple filaments spread like a fan.
Background
At 1:45 a.m. on April 21, 1957, Mde. Gilberte Ausserre and Mde. Rolande Prevost saw a yellow, hemispherical object in the sky at Montluçon, Allier, France. Its apparent diameter increased to that of the full moon before it suddenly disappeared from sight, reappearing a few minutes later to the right of its first position. It remained visible for about 5 minutes, vanished again for 5 minutes, then returned. From the underside emerged several green and purple filaments spread out like a fan; its brightness was blinding and the shape was reminiscent of a jellyfish, and at some point it appeared as a double-sided object. It disappeared completely at 2:30 a.m. The entry cites Aimé Michel's Flying Saucers and the Straight-Line Mystery, Jacques and Janine Vallée's Challenge to Science and an article by Erol Faruk in SCU Review (2026) comparing the case with Delphos. The account follows the entry in George M. Eberhart's chronology UFOs and Intelligence (CUFOS) and the sources cited there; it is not an independent determination by From Beyond Space.
