Tips

Get away from city lights and look toward the pole: north in the Northern Hemisphere, south in the Southern. Your phone camera often picks up color your eyes miss, so take a photo with a few seconds’ exposure.

This is a rough guide. Clouds and city lights are not included, and space weather forecasts can change within hours.
