Vigi-Sky — citizen astronomy and UAP observatory, launched 15 January 2026. Measurement tools, never “UFO detected”.
Sky Sentinel
Citizen observatory launched 15 January 2026: measure a light in the sky (azimuth, stars, video authenticity) without ever claiming “UFO detected”. Free, bilingual, open source.
Hatch UDB is an imported historical archive (Larry Hatch, 1900–2002). It is not added to public Vigi-Sky files, still at zero until a witness consents to publication.
📋TL;DR — Vigi-Sky in 30 seconds
Vigi-Sky is a bilingual citizen observatory (vigi-sky.fr / vigi-sky.com), launched 15 January 2026 by Christophe Boiral. Free tools to measure a light in the sky — never claiming “UFO detected”. The Hatch UDB archive (18,116 cases, 1900–2002, Larry Hatch) is an imported historical dataset, distinct from public Vigi-Sky files (still at zero).
- UFO/UAP submission with Anthropic API analysis
- Aurora borealis prediction (NOAA Kp index)
- Solar flares and CME tracking (NASA SDO/DONKI)
- World map: Hatch archive of 18,116 cases (1900–2002), not a live network
- VigiVision real-time AI camera (TensorFlow.js + COCO-SSD)
- Sky Identifier: stars, planets in augmented reality
- 3I/ATLAS tracker (3rd interstellar object detected)
- Case studies: Roswell, Rendlesham, Tic-Tac, Phoenix, Aveyron 1966
- In-depth articles: Wow! Signal, FRBs, Tabby's Star, M87*
- NASA cosmic sounds (M87, Mars, pulsars sonifications)
- P900 calculator: what to photograph tonight?
- Personalized star map for your birthday
Editorial approach: scientific, open, without automatic dismissal or credulity. Never “UFO detected”. Hatch is not a Vigi-Sky counter.
The sky right now
The live signal: observing conditions, expected celestial phenomena, solar system, Moon — not a 'UFO night' forecast.
Observing conditions and expected sky phenomena
Tonight's sky-observing conditions index, computed in real time from geomagnetic activity, satellite passes, moon phase and weather — not a probability of a phenomenon. Context: 18,116 historical Hatch UDB cases.
What to watch tonight
A practical observing path: local sky, constellations, NASA picture of the day and galleries.
Aurora, Sun and passes
Fast-moving phenomena: solar activity, aurora, ISS, celestial calendar and galactic map.
Deep signals
Big cosmic files: M87*, gamma ray bursts, Wow!, FRBs, Tabby's Star, Fermi and simulations.
Observe and analyze
The field layer: physics lab, observation map, report submission and AI analysis.
UAP archives and nearby cases
Long-range data: 3I/ATLAS, Black Knight, world map, nearby cases, historical studies and timeline.
Field tools
The immersive toolbox: VigiVision, witness generator, P900, birth sky and cosmic sounds.
Network and learning
Starlink, citizen science, ranking and learning content in the same scroll.
AI lab
Exoworld creation, time machine, recurring patterns, AI arena and celestial copilot.
Articles and field notes
The editorial exit of the journey, keeping depth and updates in the same place.
