Summary:
Anyone troubled by storms on the Sun will now have an extra week's early warning of eruption risks, courtesy of the Solar and Heliospheric Observatory (SOHO) spacecraft. Teams in the United States and France have found two different ways of detecting activity on the Sun's far side before it swings into view from the Earth.

Anyone troubled by storms on the Sun will now have an extra week's early warning of eruption risks, courtesy of the Solar and Heliospheric Observatory (SOHO) spacecraft. Teams in the United States and France have found two different ways of detecting activity on the Sun's far side before it swings into view from the Earth. SOHO's Solar Wind Anisotropies (SWAN) instrument sees ultraviolet rays sweeping like a lighthouse beam across interplanetary gas beyond the Sun, while the Michelson Doppler Imager (MDI) instrument peers right through the Sun to locate hidden sunspots and their active regions. Both teams are now making their observations available routinely to everyone, including the forecasters of space weather.
