Performance of ERNE in particle flux anisotropy measurement

Valtonen, E.; Lumme, M.; Riihonen, E. +3 more

The HED particle detector of the ERNE experiment to be flown on the SOHO spacecraft is unique compared to the earlier space-born detectors in its high directional resolution (better than 2°, depending on the track inclination). Despite the fixed view cone due to the three-axis stabilization of the spacecraft, the good angular and temporal resoluti…

Energetic particle investigation using the ERNE instrument

Vainio, R.; Valtonen, E.; Eronen, T. +9 more

During solar flares and coronal mass ejections, nuclei and electrons accelerated to high energies are injected into interplanetary space. These accelerated particles can be detected at the SOHO satellite by the ERNE instrument. From the data produced by the instrument, it is possible to identify the particles and to calculate their energy and dire…
