Countdown to 2026/9/23 "Black Autumn Equinox": Parker and Biggs, power outage × solar storm...

This is not intimidation, but reconciliation. The film opens with three verifiable blackouts: Spain and Portugal lost 60% of their loads in five seconds on April 28, 2025, a nationwide chain power outage in Chile on February 25, 2025, and the entire island of Cuba went to zero multiple times, plus London's Heathrow substation was paralyzed due to a fire. Then we enter the maximum period of the 25th solar cycle: G5 level geomagnetic storm, X9.0 flare, difference between CME and flare, 1-3 days warning window and black start risk; review of the Carrington incident, the 1989 Quebec power outage, the 2003 Halloween series of storms and the "pass by" in 2012. At the bottom of science, the Russell-McFerran effect is used to explain why the vernal and autumnal equinoxes are most likely to cause serious problems. On the prophetic side, we compare Craig Hamilton Parker’s repeated blackout imagery over the years with Brendan Biggs’ vision in “The Darkness After the Assassination,” and position “Black Equinox” as an intersection of imagery × astronomy, rather than a single point of endorsement. Finally, three scenarios were deduced: 1) a high-probability regional power grid accident; 2) a low-probability and high-impact solar storm spread; 3) nothing happens, the prediction fails but the risk remains. The practical section provides a 72-hour household checklist: flashlights and backup power, small cash notes, drinking water, battery-operated radios, as well as details such as a fully charged mobile power supply, a half-full gas tank, and a gathering point for family members. This is a complete inventory that aligns the lines of science, engineering, journalism and prophecy: When the date is drawn on 2026/9/23, we choose to replace panic with preparation.
