Northern Lights: a how-to guide

There are few phenomena that capture the imagination like the Aurora Borealis. The Northern Lights appear only at high latitudes on dark nights from September to March, and lucky star-gazers can witness anything from an ethereal green glow on the horizon to pulsating scarlet streaks across the sky. Countries across Scandinavia, as well as Canada, Alaska, Russia and even Scotland, are home to this seasonal spectacle and travellers cross the globe in the hope of glimpsing it.

The liveliest phase of the 11-year solar cycle is now, so it's little wonder that so many travellers are poised to search out the gleaming horizons of the north. But the Northern Lights are as fickle as they are inspiring, so aurora-hunters need a hefty dose of luck along with good planning. Weather, timing and light pollution can spell the difference between celestial wonder and a freezing night spent looking at your watch.
