AB: We present the results of a survey of FTEs in high-time resolution (6s) observations by the magnetometers on the Interball-1 spacecraft from 1995 to 1999. The orbit of Interball-1 permitted the spacecraft to observe the low- and mid-latitude (~50 degrees) dayside and flank magnetopause. We have identified more than 500 FTEs over a wide range of latitudes and longitudes. They typically exhibit amplitudes in the range from 6 to 20 nT. The direction of event motion can be determined from the sense of the magnetic field component normal to the nominal magnetopause. Both northward (+,-) and southward (-, +) moving events have been observed over the full range of latitudes covered. We present case studies of the structure of individual events and the results for event occurrence and motion as a function of solar wind conditions and location on the magnetopause. We use simultaneous Wind, Geotail, or IMP-8 observations to determine prevailing solar wind conditions and event occurrence patterns and thereby discriminate between proposed models for event generation.
