Number 382 (Story #2), July 17, 1998 by Phillip F. Schewe and Ben Stein
A SUN-EARTH CONNECTION EVENT, in which a gust of plasma particles (a coronal mass ejection) detaches from the Sun and travels all the way to our planet, where it causes electromagnetic disturbances and atmospheric auroras, has been monitored from start to stop for the first time. The International Solar-Terrestrial Physics Observatory, a network of ground-based and satellite detectors, watched the drama play out over the period January 6- 11, 1997. The absence then of notable surface features on the Sun, such as flares, reinforces the notion that coronal rather than surface activity is more important for determining near- Earth space storms. (Several articles in the 15 July 1998 issue of Geophysical Research Letters.)
