Overview
- NOAA confirmed G4 conditions this week with geomagnetic indices reaching about Kp 7–8, and the agency said G4 remains possible into Thursday night.
- Auroras were seen far beyond typical latitudes, with reports from Florida, Texas and Mexico in the Northern Hemisphere and vivid displays across Australia and New Zealand.
- NOAA’s Space Weather Prediction Center said multiple CMEs have hit Earth and a faster third arrival was expected late Wednesday into Thursday, keeping watches in effect.
- Operational knock‑ons included a postponement of Blue Origin’s New Glenn launch, and infrastructure operators were alerted to potential navigation and communications disruptions.
- The surge comes as Solar Cycle 25 nears its peak, and forecasters say elevated solar activity is likely to continue into 2026, offering more opportunities for low‑latitude sightings when skies are clear.
