We rely on advanced technology for almost everything we do today. Satellite communications, GPS applications, and the electric power grid provide the backbone to our Nation’s economic vitality and national security. This technology however, is vulnerable to a threat from space — our Sun. Eruptions from the Sun can have a profound impact on society. In Boulder, Colorado NOAA space weather forecasters maintain a constant vigil on the Sun, alerting a diverse customer base when storms are imminent. Operators from many sectors will take mitigating actions to protect the critical infrastructure that we have come to depend on.
