Overview
- NOAA’s Space Weather Prediction Center confirmed the event reached G4 severity, the second-highest level on its geomagnetic scale.
- Auroras were documented across a wide swath of the U.S., with sightings from New England to California and unusually far south into Florida and Texas.
- SWPC projected additional CME impacts into Wednesday night and Thursday with timing uncertainty, keeping storm watches in effect and raising the chance of renewed displays.
- Officials reported communications and navigation anomalies and warned grid operators, while NASA postponed a Blue Origin rocket launch carrying Mars orbiters and UC Berkeley noted satellite delays tied to the storm.
- Meteorologists point to the Sun’s approach to solar maximum as a driver of heightened activity through 2026, and advise viewers to seek dark skies after nightfall and use smartphone night modes or long exposures.
