We examine interplanetary data and geomagnetic activity indices during 1974 when two long-lasting solar wind corotating streams existed. We find that only 3 major storms occurred during 1974, and all were associated with coronal mass ejections. Each high speed stream was led by a shock, so the three storms had sudden commencements. Two of the 1974 major storms were associated with shock compression of preexisting southward fields and one was caused by southward fields within a magnetic cloud. Corotating streams were responsible for recurring moderate to weak magnetic storms.

Energetics of Superstorms

For the most intense storms of the space era, for which there is good solar wind data coverage, we discuss the total energy and power degradation during the storm development, beginning at the solar wind, then at the solar wind-magnetosphere interface (magnetopause) and at the magnetospheric tail, ending at the two basic inner magnetospheric dissipation regions: the ring current and the auroral ionosphere.

Cost-Effective Mission Design for a Small Solar Probe

The Small Solar Probe Mission is designed to characterize the Solar Corona as close as three solar radii above the sun's surface. Until 1992 studies generated concepts with large spacecraft launched on large launch vehicles and requiring nearly a decade to reach their initial perihelion.

Report From The Breckenridge, Colorado Magnetic Storm/Substorm Workshop, June 24-27, 1993

Magnetic storms have not received the same amount of attention as substorms for the last several years due to a number of factors: there has been a stronger emphasis toward the.
