Eclipse Run vs Light Pollution Map

Eclipse Run lets you pick the best spot for you to experience—live and in person!—Available in two languages (English and Spanish) it covers the eclipse of August 12th 2026 (From Iceland to Spain), and with Plan Ahead you get a bonus eclipse, that of August 2nd 2027. This app shows maps marking the zone where you can see the total eclipse. In the middle of the zone, is the line of maximum totality (over 2 minutes, depending on the location) The app now gives you the approximate duration of the eclipse at all spots within the zone of totality. The maximum totality for the bonus eclipse is over 6 minutes. You just hold your finger on various spots at intersections between this line of maximum totality and a road. A dot appears. Next, by tapping on that dot, you can learn what the weather will be like at your desired location. Plus you’ll get detailed driving instructions via Maps. On your journey, Eclipse Run gives you alerts when you enter the zone of totality, and when you cross the line of maximum totality. It’s easy to understand. It will help you experience this miracle of nature—totally! The Plan Ahead feature, will give you even more information, such as historical average cloud cover and more!

The map displays VIIRS/World Atlas/Clouds/Aurora/IAU observatories and the user SQM measurements. The primary use is to show VIIRS/DMSP data in a friendly manner, but over time it also included some other interesting overlays that concern light pollution like SQM/SQC, World Atlas 2015 zenith brightness, clouds, aurora and IAU observatories. If you have a permanent SQM reader installed you can add it to the map by sending me an e-mail.
