Near-earth Reconnection Event Observed By Cluster On August 27, 2001. A Case Study.
Abstract
Data from the four Cluster satellites and ground based observations are used to the study effects of a near-Earth reconnection event in August 27, 2001. At about 0400 UT this day, the four Cluster spacecraft were located about 20 Re downtail in the plasma sheet. A strong rotation of the magnetic field combined with tailward flow velocities in excess of 500 km/s observed at Cluster suggest that a strong reconnection event took place earthward of 20 Re. Ground based observations near the magnetic footpoint of Cluster and global images from the POLAR UVI experiment show increased auroral activity as a result of the reconnection event. In this presentation we specifically try to address timing and propagation effects of the observed features.
