Nightside magnetosheath of Mars: ASPERA observations
Abstract
We have calculated the proton and the oxygen velocities in the nightside magnetosheath of Mars utilising the particle observations made by ASPERA onboard the Phobos 2 spacecraft. The O^+ observations can be divided into three classes according to the velocities and locations: the ``central tail'', the ``energetic'', and the ``slowly moving'' O^+ ions. A detailed study of the energetic O^+ ions shows that they are related to non-typical magnetic field conditions.
