Overview

• NOAA’s Space Weather Prediction Center forecasts a G1 geomagnetic storm this morning with chances of isolated G2 activity as charged particles from a July 23 coronal mass ejection brush past Earth.
• The Kp index is expected to peak at level 5 between 09:00 and 12:00 UTC, signaling moderate auroral activity visible on the northern horizon.
• Skywatchers across 14 U.S. states—from Washington and Idaho through New England—and nearly all of Canada, including southern Ontario, Quebec and the Maritimes, are positioned to catch pre-dawn displays.
• The outlook builds on data from Spaceweather.com and NASA’s WSA-Enlil model, which tracked the CME’s trajectory before impact.
• The current solar maximum, the most intense in over two decades, is driving unusually active summer auroras and is expected to sustain heightened displays through at least 2026.
