Aurora across all of South Dakota

Northern lights in South Dakota — FAQ
Can you see the northern lights in South Dakota?
Yes, on the right night. South Dakota needs the planetary Kp index to reach Kp 7 for the aurora to appear low on the northern horizon. That happens during geomagnetic storms — Cosmik shows tonight's live odds above so you know before you drive out.
What Kp does South Dakota need for the northern lights?
South Dakota needs a Kp of about 7 for the aurora to become visible from a dark site with a clear northern horizon. That figure comes from the state's geomagnetic latitude (52°): the higher your geomagnetic latitude, the lower the Kp you need.
When is the best time to see the aurora in South Dakota?
Look between about 10 pm and 2 am local time, on a clear, moonless night, from a spot with no light pollution and an open view to the north. The season peaks September–March, and geomagnetic storms are most frequent near the equinoxes. Cosmik tracks the live Kp so you can catch the exact night it spikes.
