Thunderstones was created to show you the best possible day, time, and viewing angle for experiencing meteor showers. Set yourself up perfectly to witness the true beauty of the cosmos with Thunderstones' helpful features:
Visibility Score - calculates the moon phase, cloud coverage, and light pollution into one simple score to help find the best day to see your meteor shower.
Upcoming Events - all major meteor showers in a quick access table with the projected visibility score for each day!
Radiant Point Locator - points to the origin point of the meteor shower in the sky for best viewing angles, also, taking into consideration that at times the meteor trajectory could start below the earth and follow that path over a period of time.
PRO TIP: Thunderstones tracks these night sky events all around the world. Point the locator toward the ground to see activity on the other side of the world!
