Magnetic storms may cause damage to satellites, radiation hazard to astronauts, disruption of radio communications, and interruption of ground electric power lines. Space weather prediction is becoming an important issue to be addressed in the twenty-first century. The International Solar Terrestrial Program (ISTP) employs five satellites to probe the solar wind and magnetosphere, providing valuable information for space weather prediction.

In order to provide a forum to discuss the many new results in this rapid-moving field and to forge international collaborations, a three-day Cospar Colloquium on "Space Weather Study Using Multipoint Techniques" was held. This colloquium provided a forum for experts from the international community to present new results on the timely topic "space weather."
