Observations of shock acceleration signatures by Ulysses: the 04:08:16, day147, 1991 UT shock

Sarris, E. T.; Anagnostopoulos, G. C.; Marhavilas, P. K.

We analyze the acceleration signatures of energetic ions (E>50keV) and electrons (E>30keV) observed on day 147, 1991 UT in the vicinity of the surface of a fast-mode hydromagnetic shock, using fine time resolution measurements by the HI-SCALE instrument onboard the Ulysses spacecraft. The observations present strong evidence for the accelera…
