Title :Scientists warn solar activity could hit London 2012 Olympic Games
Scientists from NASA warned yesterday that the solar activities may go to extreme during the 2012 London Olympic Games, which might cause great interference on the satellite and electrical communication devices. By now it is impossible to predict solar flare and magnetic storms in advance.
Next Saturday NASA's solar observatory will be launched from Cape Canaveral. It will orbit around the earth for five years. Fluctuations of the sun's ultraviolet output, magnetic field and atmosphere of the sun will be the main targets. Then the observatory will send back these images with a much higher resolution at real time. Enormous data will be transferred to earth every day.
Previous warning is based on two recently forming solar flares, indicating a strong activity of the sun. Launch at this time will be of great help for people to investigating the sun.(140words）
