Northern lights from Sierra Vista

Sierra Vista lies at 38.6° geomagnetic latitude. That is south of where even the strongest G5 (Kp 9) storms usually reach, so aurora is a once-in-decades event here. The card above compares tonight's NOAA forecast with that level. See northern lights in Arizona for the best places to watch.

Dark skies near Sierra Vista

City lights wash out faint stars, meteors and the Milky Way; even half an hour's drive away from the lights makes a big difference. The nearest certified dark-sky places to Sierra Vista:

Questions and answers

When is the best time to see the Geminids from Sierra Vista in 2026?

On the night of Sun, Dec 13, from about 1:06 AM to 3:46 AM, when the radiant is highest in Sierra Vista's dark sky. Under a dark sky you could see up to about 150 meteors an hour at the best time; city lights cut that a lot. 23% Moon, down during the best hours.

Can you see the northern lights from Sierra Vista?

Only in exceptional storms. Sierra Vista is at 38.6° geomagnetic latitude, south of where even a G5 (Kp 9) storm usually reaches, although the extreme storm of May 2024 was photographed this far south in places.

Around each New Moon, when the Moon is out of the sky for most of the night. In December 2026 the moon-free stretch is Dec 2–14 and Dec 31. The longest astronomical night of the period is Dec 6, with 11 h of full darkness.
