Joe Hirman,deputy chief of the Space Environment Services Centre (SESC),Boulder,Colorado,poses by one of the Center's solar telescopes. Operated by the National Oceanic and Atmospheric Administr- ation,the SESC is one of only four places in the world that forecast solar weather & its impact on Earth. Sunstorms can dramatically affect life on Earth; geomagnetic storms cause power surges,disrupt telecommunications & interfere with navig- ational systems. The Center can alert the world to an impending magnetic storm within minutes. Solar activity is continuously monitored via a network of magnetometers,cosmic ray detectors,ground- based solar telescopes,and orbiting satellites | |
