G2 – Moderate geomagnetic storm in progress, auroras possible from New York to Washington state

A positive polarity coronal hole high speed stream currently interacting with Earth’s magnetic field produced a G2 - Moderate geomagnetic storm, with the K-index peaking at 6 at 20:00 UTC on February 16, 2026. The storm may generate visible aurora across northern U.S. latitudes and cause minor operational effects in satellite and power systems. Source
