Sky on Fire Tonight: Giant ‘Solar Canyon’ Aims 800‑km/s Wind at Earth—Northern Lights Could Ignite 15 U.S. States & Test Global Tech
NOAA’s Space Weather Prediction Center issued a G2 (moderate) geomagnetic‑storm watch for the night of 25 June 2025. A negative-polarity coronal hole crossing the Sun’s central meridian is releasing plasma at roughly 500–800 km/s toward Earth. The fast solar wind could drive auroras as far south as Colorado, New York and Oregon and briefly disturb power grids, satellites and GPS. Peer‑reviewed modeling in Nature Scientific Reports shows high-speed streams routinely trigger medium geomagnetic storms that can inject more energy into near‑Earth space than rarer CMEs over a solar cycle. A compressed co-rotating interaction region at the leading edge combined with
