Should I go out tonight, where, and when?
Most aurora apps show you a Kp number and leave the rest to you. Aurora Atlas answers with a decision: the best spot within your drive tonight, and the hours to be there.
Free. Aurora Tromsø Northern Lights is now Aurora Atlas: the same app, and your settings come with you.
What it does
One question, answered: is tonight worth it, where should I go, and when?
A plan, not a chart
Every viewing spot gets a score from 0 to 100 for tonight from clear sky, aurora activity, darkness and the moon. You get one recommended place, the best three-hour window and a Navigate button.
Clouds, done properly
Cloud decides most aurora nights. Atlas reads low, mid and high cloud for every hour at every spot, because thin high cloud and thick low cloud are not the same night. It can tell you when a drive inland gets you under clear sky.
Local detail, destination by destination
Hand-picked viewing spots with drive times, parking, bus stops and winter notes, the same care first built for Tromsø, now at 35 destinations and more on the way. Anywhere else, the app scores the place you pick.

Made in Tromsø
41 spots around Tromsø, with cameras and road notices
Aurora Atlas started as Aurora Tromsø, built by a Tromsø local to answer the question visitors ask every evening. The Tromsø guide is the most detailed in the app: 41 named spots from Telegrafbukta in town to the Lyngen Alps, with drive times from where you stay, bus stops and parking, live sky and road cameras, and road notices on the map.
Destinations
A score for anywhere, spots where we know them
Pick a base and how far you will drive, and the app ranks the hand-picked spots within reach; pick any other place on Earth and it scores that place. Zoom out to the globe to see tonight's measured aurora oval (NOAA OVATION), or where on Earth it is dark right now.
