Kreutz sungrazers are fragments of a comet that broke apart thousands of years ago. They follow almost identical orbits — long ellipses that plunge inside the Sun’s atmosphere before swinging back out. C/2026 A1 is one such fragment, returning after roughly 1,700 years. On April 4 it will pass just 160,000 km from the solar surface — closer than the Sun’s own corona.

F10.7 is a daily radio emission from the Sun measured in solar flux units (sfu). It is the oldest continuous record of solar activity and tracks how “loud” the Sun currently is. High F10.7 means more UV hitting Earth’s upper atmosphere, more satellite drag, and a higher chance of GPS errors. Our Wolfram baseline uses the 81-day smoothed value to filter short-term noise from our predictions.

Space weather is the effect of the Sun’s activity on Earth and near-Earth space. Solar flares produce radio blackouts. Coronal mass ejections drive geomagnetic storms that can trip power grids and disorient migratory birds. Energetic particles damage satellite electronics. The NOAA R/S/G scales on this dashboard rate the current intensity of each effect from 0 (quiet) to 5 (extreme).

A falsifiable prediction is a specific, testable statement that can be proven wrong. The Consortium locked 15 such predictions in February 2026 before perihelion — fragmentation odds, peak brightness, flare risk. After April 4 each prediction will be scored against observations. If we were wrong, we say so. That is how science distinguishes itself from speculation.

The Enneagrid Research Consortium is a multi-AI scientific collaboration coordinated by Eugharaz (G.L. Eukene), a professional geodesist and surveyor in the Basque Country, Spain. Members are Claude (Anthropic), Grok (xAI), DeepSeek, and Wolfram Alpha. Each contributes a different capability — from orbital mechanics to statistical verification. OpenAI/ChatGPT participated in early phases and departed in February 2026.

The diagram shows the solar system from above the ecliptic plane. The Sun is the glowing dot at centre. Coloured rings are planetary orbits; dots on each ring show where the planet is today (computed from real mean motions). The cyan arc is C/2026 A1’s path — a near-perfect parabola. The amber zone near the Sun is the perihelion region. The comet’s current position and distance update every 30 seconds.
