Northern lights in Utqiaġvik (Barrow) tonight · live
Can you see the aurora in Utqiaġvik (Barrow)?
Yes. From a dark site you need about Kp 0 for a faint glow low on the northern horizon, and roughly Kp 2 for bright aurora directly overhead. At 70° geomagnetic latitude this spot sits deep under the auroral oval — quiet nights are often enough.
Over the last 12 months the planetary Kp peaked at the levels Utqiaġvik (Barrow) needs on the days shown — out of 365. Kp is a global index, so these are the odds the sky was active enough; you still need clear, dark skies here. In 94 years on record the strongest day hit Kp 9.

Thresholds are averages from a dark site. Real visibility also needs clear skies, darkness and a cooperative moon — read every number as a chance, not a guarantee. The map is schematic: the oval is drawn around the geomagnetic pole and tuned to this place, so its edge reaches the marker at the Kp this page gives; the marker is approximate.
