How to see the aurora from Trelew
Get away from city lights — even 20–30 minutes out makes a big difference.
Face south and find a clear, low horizon in that direction.
Let your eyes adjust to the dark for 15–20 minutes.
Check the live forecast before you head out — and again once you're there.
Bring a camera or phone in night mode; faint aurora often shows on camera before the eye.
