Tonight's Decision
A practical aurora forecast for Dunedin, New Zealand, built around visibility, cloud risk, and whether it is worth going outside tonight.
Checking Kp, Bz, solar wind, moonlight, and local cloud cover.
Dunedin is an aurora viewing location in New Zealand at latitude -45.88 and magnetic latitude -49.4. This page summarizes whether aurora is practical tonight using Kp index, Bz, solar wind speed, moon illumination, cloud cover, and a 0-100 Aurora Visibility Score.
Use the Aurora Visibility Score at the top of this page as the fast decision signal for Dunedin. A higher score means stronger geomagnetic activity, better sky clarity, and a more practical chance of visible aurora tonight.
Dunedin sits near magnetic latitude -49.4 degrees. Higher-latitude destinations can see aurora at lower Kp values, while lower-latitude cities usually need a stronger geomagnetic storm.
Cloud cover is a major local risk. Even strong aurora activity can be hidden by overcast skies, so clear breaks are often more important for a real viewing decision than small changes in Kp.
The practical viewing window is usually late evening through the early morning hours, with the best chance after full darkness and away from city lights.
