A 30 July 2026 M1.9 flare produced an Earth-directed partial-halo CME, and model runs projected arrival at Earth by early 2 August with G1-G2 geomagnetic storm conditions. Even when not severe, repeated CME impacts stress satellites, surface power systems, and forecasting networks that a lunar civilization backup would depend on. [3]
