Despite decreasing geomagnetic activity, the Northern Lights might still be visible tonight, June 3, 2025. Earth is still experiencing effects from coronal mass ejections (CMEs) that impacted on June 1st and June 2nd, causing geomagnetic disturbances.
The U.K. Met Office indicates a slight chance of strong (G3) geomagnetic storms, with minor (G1) and moderate (G2) intervals also anticipated. The NOAA Space Weather Prediction Center forecasts the Kp index to peak at 4.67 in the next 24 hours.
Alaska has the highest likelihood of seeing the Northern Lights in the U.S. tonight. If G3 storms occur, auroras might be visible as far south as Illinois and Oregon, though this is less probable. For optimal viewing, find a location facing north, away from city lights, around 1 a.m. local time. Mobile phone cameras can help detect faint auroras, and space weather apps provide forecasts based on your location.
