Why Ushuaia

The world's southernmost city, at the tip of Tierra del Fuego and closer to the pole than almost anywhere inhabited.

How much activity you need here

At 54.8° geographic latitude, aurora typically becomes visible here once the planetary Kp index reaches about 6. Stronger geomagnetic storms push the oval overhead and light up more of the sky.

Best time to go

The southern aurora season runs from mid-March to late September, when the long southern-hemisphere nights give real darkness. Midsummer (December–January) is too bright for aurora at these latitudes.
