Can you see the northern lights in Georgia tonight?
Unlikely tonight. Kp is 1.00 at 3:37 PM EDT, and Georgia needs about Kp 9 before the aurora reaches its northern horizon.

Sky tonight
Partly cloudy, 70% cloud
Kp from NOAA SWPC estimated planetary K index, read at 3:37 PM EDT. Cloud cover for Cloudland Canyon State Park from the National Weather Service FFC gridded forecast.
Why Georgia needs Kp 9
The aurora follows the Earth's magnetic field rather than the equator, so what matters is geomagnetic latitude, not the number on a map. The northern edge of Georgia sits at 44.1° geomagnetic. The auroral oval reaches that far south at about Kp 9, allowing for the five degrees of extra reach you get from aurora sitting high in the atmosphere and showing low on the horizon.
Cloud is the usual reason a good Kp night comes to nothing. At Cloudland Canyon State Park, in the north of the state, tonight is forecast partly cloudy at 70% cover, with the clearest hour around 9:00 PM.
The next three days
NOAA's three-hour Kp outlook. The highest expected value is Kp 4.00, which stays below the Kp 9 Georgia needs.

Watching from Georgia
- Look north, low on the horizon. From Georgia the aurora rarely climbs overhead.
- Get away from town lights and give your eyes twenty minutes to adjust.
- The most active hours are usually between 10pm and 2am local time, around magnetic midnight.
- A phone on a three to five second exposure will pick up colour your eyes cannot, so a grey glow to the naked eye can still photograph green.
