Can I See the Aurora Tonight?

Live viewing chances across 11aurora destinations, ranked by tonight's conditions.

Current Kp index: 6.00 (Moderate Storm)

How Rankings Work

Each city is scored from 0 to 100 based on three factors: the auroral activity directly overhead (from NOAA's OVATION model), whether the current Kp index meets that city's visibility threshold, and whether the sky is currently dark. A city in daylight is capped low no matter how strong the activity, because the aurora simply can't be seen against a bright sky.
