Reporting Auroras from the Ground Up since 2012! Aurorasaurus is the world's first free mobile app to put citizen science and crowd-sourced (Twitter) ground truth observations of aurora on a real-time Google map along with weather and predictions for where the Northern Lights should be visible. When aurora occurs near you, we will let you know promptly and in simple language to increase your chances of spotting this beautiful, rare sight.
Additional features include the capability to register and receive location-based notifications, a real-time monitor of space weather activity, the capability to help verify tweets and search for real sightings, the answers to your questions, and more. We are free of charge and advertisements.
