Can you see the aurora in Punta Arenas?

Yes. From a dark site you need about Kp 9 for a faint glow low on the southern horizon, and roughly Kp 9 for bright aurora directly overhead. At -44° geomagnetic latitude this spot sits well outside the oval — it takes a major geomagnetic storm.

◇ How often, historically
0 / 365
days · Kp 9+ (overhead here)

Over the last 12 months the planetary Kp did not reach the level Punta Arenas needs on any of its 365 days — it takes a rare, major storm. Kp is a global index, and you still need clear, dark skies here. In 94 years on record the strongest day hit Kp 9.

When to go

The season runs late March to late September, when the nights are long and dark. You also need clear skies and a low moon — even a strong Kp is useless under cloud. Check tonight's live call above, then plan a night around the dark window, cloud and moon.

◐ Tonight: about 10.3 h of astronomical darkness (~18:54–05:10 local). The aurora is usually best near local midnight.

Thresholds are averages from a dark site. Real visibility also needs clear skies, darkness and a cooperative moon — read every number as a chance, not a guarantee. The map is schematic: the auroral oval is drawn at a nominal 66° and the marker is approximate.
