| Summary: | The Double Star TC-1 magnetosheath pass on 26 February 2004 is used
to investigate magnetic field fluctuations. Strong compressional
signatures which last for more than an hour have been found near the
magnetopause behind a quasi-perpendicular bow shock. These
compressional structures are most likely mirror mode waves. There is
a clear wave transition in the magnetosheath which probably results
from the change of the interplanetary magnetic field (IMF) cone
angle. The wave characteristics in the magnetosheath are strongly
controlled by the type of the upstream bow shock. |
