Beyond the headline fragmentation and magnitude forecasts, the Consortium locked ten detailed observables. Prediction 3 pins peak brightness to within 3 hours of perihelion. Predictions 4 and 5 quantify the tail and fragment count. Prediction 6 forecasts naked-eye visibility ending around April 21. Prediction 7 expects SOHO to detect the comet in its coronagraph field. Prediction 8 anticipates 3 ion tail disconnection events as the comet crosses solar wind boundaries. Prediction 9 is independent — it forecasts the brightness of a second comet, PanSTARRS C/2025 R3, peaking around April 20. Prediction 10 holds that no spacecraft will detect the comet in situ — 85% confident. All will be scored against official archive data in May 2026.

Prediction 16 forecasts that over 99% of operational satellites will survive through May 2026 — but it is not a prediction that nothing will happen. It is a prediction about a coupled physical and human system. The Consortium locked this number knowing that space agencies and commercial operators (SpaceX, ESA, JAXA, and others) would likely take proactive protective action — raising satellite perigees, adjusting drag profiles, and pausing scheduled deorbits — in response to elevated geomagnetic storm probability around perihelion. Planned maneuvers are not counted as losses. A >99% survival outcome achieved through operator action is a fully confirmed prediction, not a lucky escape. This framing is intentional: it recognises that human response to good science is itself part of the scientific outcome.
