Overview
- NOAA forecasts a Kp index of up to four out of nine from June 23 to 25, signaling moderate geomagnetic activity and visible auroras
- Displays are expected in eight border states—Alaska, Washington, Idaho, Montana, North Dakota, Minnesota, Wisconsin and Michigan
- Optimal viewing runs nightly from 10 p.m. to 2 a.m. local time in dark, north-facing areas away from light pollution
- There is a slight chance of minor S1 solar radiation storms over the same period due to eruptive regions on the sun’s visible disk
- No special instruments are required to see the lights and photographers can use smartphone night modes or a dedicated camera with a wide-angle lens and tripod
