Seeing the northern lights from Avondale, AZ
Avondale sits at about 33.4°N. The aurora becomes visible here only when a geomagnetic storm expands the auroral oval far enough south to reach your latitude — roughly Kp 9 or stronger. Storms that strong reach this far south only a handful of nights a year, most often near the peak of the Sun's 11-year activity cycle (which we are close to now).
When a storm is in range, find a spot with a clear, dark view of the northern horizon, away from city lights, after evening twilight ends. This far south the aurora usually shows as a low green or red glow near the horizon rather than overhead curtains — a camera often captures it before your eyes do.
A bright moon or clouds will wash out a faint display, so the best nights pair a strong storm with clear, dark skies. Check back here on active nights for the current odds in Avondale.
