Nearest Active Aurora: How Nearby Spot Finder Works
Learn how Nearest Active Aurora in Aurora Forecast finds nearby places with current activity using distance and multi-factor visibility checks.
Nearest Active Aurora helps answer a practical question: "If I cannot see aurora right here, where is the closest place with better conditions right now?"
What the Feature Returns
The app returns up to three nearby locations with active conditions now, including distance and current status.
- Nearest qualifying places first
- Distance in kilometers from your position
- Current visibility probability and status per place
How Candidate Locations Are Chosen
Nearby search is not random. The backend builds a candidate pool around your coordinates and then evaluates each point with the same core visibility logic used in status calculations.
- Build a nearby candidate list (distance-limited).
- Load live geomagnetic and aurora data from cache.
- Apply weather + moon + darkness filters.
- Keep points that pass the activity threshold and sort by distance.
Why Nearby Results Can Differ from Your Exact Location
| Factor | Effect on Nearby Results |
|---|---|
| Cloud pockets | A place 40-80 km away may be clear while your point is overcast. |
| Darkness timing | Nearby points can move into better darkness windows earlier. |
| Aurora oval geometry | Small latitude shifts can materially change local visibility probability. |
How to Use It Efficiently
- Check your current location status first.
- If low visibility, open Nearest Active Aurora.
- Compare distance vs expected probability.
- Cross-check route weather and road safety before driving.
For route-level context, combine this with the map overlays guide.
Limits to Keep in Mind
Nearest does not always mean best photography spot
The feature is optimized for nearby active conditions now. It does not optimize for composition, local light pollution barriers, parking access, or private land constraints.
