Can you see the northern lights from where you are right now? Liminal Cosmos gives you a plain answer and shows what is in the way when the answer is no. No ads, ever.
TONIGHT, WHERE YOU ARE
• See if the aurora is in reach of your sky right now, read from NOAA's live map
• See how dark it is, how bright the moon is and how much cloud there is
• See NOAA's forecast for the rest of the night
• Going somewhere? Search any town and see the answer there
ONE MESSAGE BEFORE DARK
Turn on the evening message and one arrives each evening before your sky goes dark. It says if the aurora is in reach, and whether cloud, moonlight or daylight is in the way. Most nights the answer is no. That saves you the drive.
ALERTS
• A message when a storm starts, with what caused it and what to expect
• A message when the aurora may be visible from where you are
• A message when someone near you reports seeing it
SEEN IT? TELL OTHERS
Sign in, tap once to say you see the aurora, and add a photo if you like. See what people near you report.
PLAN AHEAD
• Trip planner: see which of the next 27 nights are your best bet where you are. A forecast weeks ahead can change, and it can't know the cloud
• Best months: see which months have had the most strong aurora nights, going back to 1932
ASK A QUESTION
The assistant answers questions about the aurora and about the app. It runs on your iPhone with Apple Intelligence, so what you ask stays on your phone. It needs an iPhone that supports Apple Intelligence, and its answers can be wrong.
THE AURORA AND THE SUN
Spin a globe that shows where the aurora is now, with your place marked. Look at the sun, its sunspots and today's pictures from NASA's spacecraft. The numbers forecasters watch are all here, and Help explains each one.
ON YOUR HOME SCREEN
Widgets show tonight's answer and the best months without opening the app.
