Aurora is visible from Texas only during rare, extreme storms. In central Texas the geomagnetic latitude is about 39°, so the northern lights usually need a Kp index of about 9.0 or higher to appear low on the northern horizon; the north of the state (around Perico) needs about Kp 9.0.

Approximate Kp for aurora low on the northern horizon (camera-visible). Higher Kp lets it climb higher and show color to the eye.

How to photograph the northern lights
- Watch the live Kp forecast above and NOAA's 30-minute aurora forecast; storms often peak between 10 p.m. and 2 a.m.
- Find an unobstructed view to the north — a lake, open field or ridge — away from town lights.
- Start at ISO 1600–3200, f/2.8 or faster, 5–15 seconds; shorter exposures keep fast-moving curtains sharp.
- Your camera sees aurora as green or red long before your eyes do — take test shots whenever Kp is near the threshold.
- Moonlight lights the foreground but washes out faint aurora; strong storms are still worth shooting under a bright moon.
FAQ
Can you see the northern lights in Texas?
Yes, only during rare, extreme storms. Central Texas usually needs about Kp 9.0; the north about Kp 9.0.
What Kp index do I need?
Roughly Kp 9.0+ for central Texas. Kp is a 0–9 scale of geomagnetic activity; each step moves the aurora's southern edge a few degrees of latitude.
Where is the best place to see the aurora in Texas?
Dark sites with a clear northern view, such as Copper Breaks State Park, South Llano River State Park, Enchanted Rock State Natural Area.
