Low in the northern sky, about 10° to 30° above the horizon. Mostly green. By eye a faint gray-white glow, like a thin cloud; a camera shows it green.
An illustration from a rule of thumb, not a photo: real aurora differs night to night even at the same Kp.

Tips for seeing it
- Look north from somewhere away from city lights, ideally between 10 PM and 2 AM local time.
- Give it time: activity comes in bursts of 10 to 30 minutes.
- A phone camera in night mode often shows colors your eyes see only as gray.
- September to March is the season: the far north has no real night in summer.
