Aurora across all of Tennessee
Tennessee only sees the northern lights during major geomagnetic storms, which can strike any month but are most likely near the equinoxes (September–March). On those rare nights, the aurora appears as a faint glow low on the northern horizon rather than overhead.

Northern lights in Tennessee — FAQ
Can you see the northern lights in Tennessee?
Realistically, no — Tennessee sits at about 44.8° geomagnetic latitude, far outside the auroral zone. It would take an exceptional, historic solar superstorm for the aurora to be visible this far south.
What Kp does Tennessee need for the northern lights?
Tennessee needs a Kp of about more than 9 (effectively unreachable) for the aurora to become visible from a dark site with a clear northern horizon. That figure comes from the state's geomagnetic latitude (44.8°): the higher your geomagnetic latitude, the lower the Kp you need.
When is the best time to see the aurora in Tennessee?
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.
