Space weather can cause both beautiful auroras and infrastructure challenges – 5 essential reads on protecting life and technology

NOAA is tracking coronal mass ejections this week that could spark a minor geomagnetic storm, with auroras possibly visible in Canada and the northern U.S. on September 9, 2026. The explainer piece, compiling academic archives, describes how solar flares and ejections interact with Earth's magnetic field to produce both auroras and disruptions to satellites, GPS, and power grids.

A 1859 solar storm shorted out telegraph lines, and researchers note a strong enough modern event could hit cell networks and electrical grids that underpin transportation and utilities. NASA has launched several 2025 missions, including PUNCH, IMAP, and the Carruthers Geocorona Observatory, to monitor the Sun from multiple vantage points, with another mission, SunCET, planned for 2027.

Experts quoted say real-time monitoring lets grid operators reroute power before a coronal mass ejection arrives, framing preparation as the main defense against a repeat of history.
