About Liminal Cosmos: Aurora & Sun
Can you see the northern lights tonight, from right where you are? Liminal Cosmos turns live NOAA & NASA space-weather data into one clear answer, then shows you why, in 3D. Most aurora apps give you a number. Liminal Cosmos gives you a verdict for your exact location, the storm behind it, and an on-device assistant you can actually ask, with nothing sent to a server. CAN I SEE IT TONIGHT? Your personal aurora forecast folds the live Kp index, your geomagnetic latitude, cloud cover, moonlight and darkness into a single visibility verdict, updated as conditions change. IT TELLS YOU BEFORE DARK Switch on the nightly verdict and one message arrives each evening, before the sky goes dark: whether tonight is worth going outside for, and what is spoiling it if it isn't. Most nights it says no, which is the point. It saves you the drive. ASK WHY, PRIVATELY A built-in assistant, powered entirely by on-device Apple Intelligence, reads the same live data you're looking at and explains it in plain language. Ask "why is Kp high tonight?" and get a real answer. The assistant runs entirely on your device, and your questions are never sent anywhere. THE AURORA, IN 3D Watch the live auroral oval wrap a real-time 3D globe, or flip to a flat heatmap. Your location is marked, so you can see exactly how close the lights are. THE SUN, IN 3D A 3D sun globe with active regions and sunspots, live SDO and SOHO imagery, and an animated SOHO/LASCO coronagraph loop: the real machinery driving every aurora. EVERYTHING THE EXPERTS WATCH Live Kp, solar wind, Bz, the NOAA R/S/G storm scales, X-ray and proton flux, and NASA DONKI events (CMEs, flares, coronal holes): the deepest space-weather data in any aurora app, made readable. ALERTS THAT EXPLAIN THEMSELVES Get notified the moment a storm makes the aurora worth chasing, with a rich notification and an alert detail that names the cause, the solar region, and what to expect. BUILT FOR PEOPLE WHO LOOK UP Whether you're chasing the lights in Iceland or tracking the sun from your backyard, Liminal Cosmos is the one app that answers both "can I see it tonight?" and "what is the sun doing?" Solar activity is high, and the years after a solar maximum have historically produced some of the largest storms. Don't miss the night it reaches you. Data from NOAA SWPC, NASA (DONKI, SDO, SOHO) and Open-Meteo. Liminal Cosmos is not affiliated with NOAA or NASA.
