GEIPAN Case 2012-06-08317 — LAMBERSART (59) 17.06.2012

Brief

At 04:00 on 17 June 2012, an amateur astronomer stepped into his Lambersart garden and observed a formation of transparent, slightly illuminated spheres passing silently overhead from south to north before dissolving into cloud cover in roughly 15 seconds. He estimated 10–15 objects, compared their appearance to soap bubbles, and described the formation as symmetric and orderly — no erratic motion at any point. The witness had already filed a report with the Air Gendarmerie at Lille-Lesquin airport but was never contacted for follow-up, which prompted this GEIPAN submission. GEIPAN assigned classification D1, denoting a strange phenomenon that remained unidentified despite usable witness data.

Key points

• Observation date and time: night of 16–17 June 2012, 04:00, Lambersart, Nord (59), France.p.3
• Single witness, age 51, amateur astronomer, observed from a wooden garden terrace while stationary.p.4
• Total duration of the event from first appearance to disappearance: approximately 15 seconds.p.5
• Objects described as transparent spheres slightly illuminated on their left flank, resembling soap bubbles.p.4
• Formation flew south-to-north in an orderly, symmetric arrangement with no erratic deviation, compared by the witness to migratory birds.p.4
• Estimated count 10–15, possibly more; transparency implied stacking on multiple depth layers, making an exact count impossible at speed.p.4
• Angular size at closest approach (near-vertical overhead): roughly the diameter of a 1-euro coin held at arm's length; a few millimetres when first spotted at distance.p.4
• No sound was produced at any point during the sighting.p.4
• The formation dissolved into a cloud bank to the north; witness continued sky-watch for approximately one hour with no recurrence.p.5
• Witness had previously reported to Air Gendarmerie at Lille-Lesquin airport by telephone and was told to appear in person; he was never subsequently contacted.p.4

Verbatim

• Cela vole dans un ordre très ordonné et symétrique à la manière des oiseaux migrateurs. Il n'y a aucune saccade ou le moindre écart dans la formation.

  p.4

• Lorsqu'elles passent pratiquement à la verticale de mon habitation, je me rends compte qu'il est impossible de les comptabiliser. Elles sont trop nombreuses et volent trop rapidement.

  p.4

• De plus, leurs transparences laissent supposer qu'il y en a sur plusieurs épaisseurs.

  p.4

• Cela ne fait aucun bruit.

  p.4

• La taille des sphères à ce moment semble être d'une pièce de 1 euro tenu à bout de bras contre quelques millimètres lorsque je les ai aperçu au départ.

  p.4

• La totalité du phénomène depuis l'apparition jusqu'à la disparition n'aura duré qu'une quinzaine de secondes.

  p.5

• A son approche, l'ensemble se dissout dans les nuages.

Most interesting

• The witness initially mistook the formation for a flock of ducks before the transparent, illuminated character of the objects resolved at closer range.
• The witness confirmed the 04:00 timestamp not from memory but from a clock check made when his daughter arrived home from a nightclub moments before stepping outside.
• GEIPAN's D1 category is reserved for cases where sufficient-quality witness data was gathered yet no prosaic explanation could be assigned — the highest anomaly tier in the French system.
• The apparent three-dimensional stacking of the spheres on multiple depth layers implies a volumetric formation rather than a flat line, which the witness explicitly noted as complicating his count.
• The sky was described as mostly clear and dark blue with only scattered clouds to the south and north, yet the witness checked 'few stars visible' on the questionnaire — conditions that should have favoured stellar observation.
• The Air Gendarmerie at Lille-Lesquin airport accepted the initial telephone report and invited the witness to testify in person, then made no further contact; the institutional gap is what routed the case to GEIPAN.
