Individuals and classrooms are invited to join the GeoMag Data Challenge! In this live event, we'll teach you how to collect data on the intensity of Earth's magnetic field using only your phone and the CrowdMag app. Your contributions will help scientists understand changes in Earth's magnetic field that will lead to improvements in navigation and help to protect our communication systems and electric grid from space weather. Individuals or entire classrooms are invited to participate! Complete your data passport to be entered into a raffle for stickers, posters, and other prizes. We are kicking off this data blitz with a live webinar on October 13th from 11:00-11:30 AM MT. Come learn about Earth's magnetic field and why it's vital for life on Earth, ask questions directly to challenge facilitators, and meet the team.
