Aurorasaurus is a citizen science project which tracks auroras through crowdsourced observations from a mobile app and social media, namely Twitter and Facebook.

[1][2] With Goddard scientist Nathan Case, MacDonald created a real-time map that displays the location of tweets that talk about auroras and have geolocation data.

[3][4] It has been developed through a collaboration between NASA, the non-profit New Mexico Consortium, Pennsylvania State University, and the company Science Education Solutions.

[4] Hundreds of citizen science observations collected by the Aurorasaurus team from March to April 2015 showed that more people reported seeing auroras closer to the equator than modeled by OVATION Prime.

[4] In 2016, Pennsylvania State University information scientists explored how Aurorasaurus could be used as an early warning system for emergency responders.
