Abstract: | The AMPTE-UKS spacecraft repeatedly crossed the dayside magnetopause during its five month period of operation (August 1984 – January 1985). We have surveyed magnetometer records from these magnetopause encounters and compiled a catalogue of flux transfer events (FTEs) using the same identification criteria as Rijnbeek et al. /1/ used in their survey of ISEE data. This catalogue comprises 59 events detected on 41 orbits. Comparing occurrence statistics we find the rate of detection of FTEs by UKS is down by a factor of 2.5 on that recorded by the ISEE spacecraft in 1977 and 1978. We suggest the lower latitude of the UKS magnetopause encounters is responsible for this discrepancy. |
