Northern lights in Ushuaia tonight

The road east of Ushuaia along the Beagle Channel shore faces south across the channel toward Chilean islands and the open Drake Passage beyond. Moving 3 km east of the city removes most of the town's light dome. The channel gives a flat south-facing dark water horizon - the key orientation for aurora australis. During Kp 3-4 events, a green arc appears low on the southern horizon and rises as activity increases. The calm channel water reflects aurora on still nights.

The national park west of the city is Argentina's most southerly protected wilderness and dark sky position. Lapataia Bay at the park's western end faces south across a sheltered inlet. The forest backdrop creates a distinctive aurora foreground. The park entrance is 12 km from Ushuaia and open 24 hours. Moving to Lapataia, at the end of the national road (Route 3's southern terminus), gives south-facing views from a position surrounded by sub-Antarctic forest. No settlements are visible from inside the park.

The road to the Martial Glacier ski centre climbs 400 m above Ushuaia and gives a south-facing panorama over the entire Beagle Channel. The city lights are behind you; the channel, Chilean mountains, and southern sky open ahead. The elevation clears ground haze and gives a wider horizon than the channel shore. Accessible by private vehicle; the road is maintained and ploughed in winter.
