Overview
- NOAA’s Space Weather Prediction Center has a G2 (moderate) watch in effect with Kp near 6, with forecasters noting a developing chance of G3 levels if the CME’s magnetic orientation favors strong coupling.
- Canada and Alaska are primed for the brightest displays, while NOAA’s view line shows potential visibility in roughly 18–20 U.S. states from the Pacific Northwest and Upper Midwest to northern New England and parts of the northern Plains.
- Multiple CMEs are expected to arrive through March 21, and a coronal hole high‑speed stream could enhance activity, with the spring equinox effect statistically boosting auroral reach.
- NOAA cautions that G2 storms can cause fluctuations in weak power grids, affect satellite operations and disrupt high‑frequency radio at high latitudes, though major impacts are uncommon at this level.
- The best viewing window is typically 10 p.m. to 2 a.m. local time under dark, clear skies; check NOAA’s 30‑minute aurora dashboard for live Bt, Bz and solar wind data, and note that southern lights could also appear in Tasmania and southern Victoria if geomagnetic activity materializes.
