Can you see the northern lights in Georgia tonight?
Unlikely: Kp 1.33 at 5:21 PM EDT falls short of the Kp 9 or so that Georgia's northern horizon requires.

Kp from NOAA SWPC estimated planetary K index. The NWS GSP gridded forecast provides cloud cover for Black Rock Mountain State Park.
At Black Rock Mountain State Park, nautical darkness begins at 8:07 PM and holds until 6:36 AM EDT. Tonight's moon, in its last quarter phase, shows 40 percent lit. The sun and moon positions, computed for the date and the viewing spot, supply both numbers, and no forecast plays a part.
What is Kp?
A 0-9 scale called Kp rates the current disturbance of Earth's magnetic field. Its name comes from planetarische Kennziffer, German for planetary index. Thirteen observatories worldwide take the measurements. Higher values mean the aurora reaches further south. Most of the northern US needs a Kp of 5 or higher, while northern Alaska sees it at Kp 0. Full Kp guide.
Why Georgia needs Kp 9
Because the aurora follows the magnetic field rather than the equator, geomagnetic latitude matters more than map latitude. At Georgia's northern edge, the reading is 44.1° geomagnetic; the oval only draws level with that latitude at about Kp 9, and the Kp number already includes roughly 5 degrees of cushion, because the high-altitude aurora hangs low on the horizon.
Where to watch from in Georgia
All three spots in Georgia can differ in cloud cover, so all three are worth a look. Black Rock Mountain State Park looks clearest tonight, at 91% cover.
| Spot | Cloud tonight | Clearest hour | Nearest town |
|---|---|---|---|
| Black Rock Mountain State Park | 91% Overcast | 11:00 PM EDT | Clayton |
| Fort Mountain State Park | 92% Overcast | 10:00 PM EDT | Chatsworth |
| Tallulah Gorge State Park | 91% Overcast | 9:00 PM EDT | Tallulah Falls |
Georgia gets its aurora during the rare G5 storm, and Black Rock Mountain State Park near Clayton is a good perch. Fort Mountain State Park near Chatsworth is another high option. Tallulah Gorge State Park near Tallulah Falls is a third. Only about four days per cycle offer this chance, so any cloud-free night matters.
Can the northern lights reach Atlanta and Savannah tonight?
| City | Kp needed | Right now |
|---|---|---|
| Atlanta | n/a | No chance |
| Savannah | n/a | No chance |
Each city's Kp value comes from its own coordinates and geomagnetic latitude, so the further south a city is in the state, the higher the Kp it needs.
Cloud cover, averaged over tonight's viewing window for each location, comes from NWS gridded forecasts.
Was there aurora last night in Georgia?
The night of October 3 topped out at Kp 3.00, short of the 9 Georgia needs, so the aurora stayed out of range.
The most recent night in range was May 10, 2024, when the night's highest Kp reached 9.00.
0 nights so far in 2026 have been in range for Georgia, against a yearly average of 0.1 across the complete years since 1994. The year's highest night Kp so far is 8.67, set on January 19, 2026.

Local time 9 pm to 3 am is the span of a night. The night's Kp is the highest among the three hour windows overlapping those hours. A night is in range when that Kp reached the threshold the state needs, which comes from where the northern edge of the state sits in geomagnetic latitude. Cloud is not in the record, so in range means the aurora was in range, not that anyone saw it. Figures are NOAA Space Weather Prediction Center daily geomagnetic data from 1994 on.

Watching from Georgia
- The aurora seldom appears overhead in Georgia; look at the northern horizon instead.
- Away from town lights, allow 20 minutes for your eyes to adjust.
- The aurora is most active from 10pm to 2am local, near magnetic midnight.
- A phone exposure of 3-5 seconds picks up color the eye cannot; a grey glow can photograph green.
