Never miss the chance to see an aurora!
If you're into auroras, you probably know that the one most important thing to look out for is the planetary KP value, which is measured and calculated by various institutions that operate magnetometers around the world.
This app monitors the KP value 24/7, and alerts you when it's high!
You can select at which level you want the alert to come, and you can also enable to get an hourly update if you like.
Unlike other apps and services that you have to pay a subscription for, this app comes with no additional costs.
支援平台：iPhone, iPad
