Collisionless shocks play a significant role in the solar wind interaction with the
Earth. Fast forward shocks driven by coronal mass ejections or by interaction of fast
and slow solar wind streams can be encountered in the interplanetary space,
whereas the bow shock is a standing fast reverse shock formed by interaction of the
supersonic solar wind with the Earth magnetic field. Both types of shocks are
responsible for a transformation of a part of the energy of the directed solar wind
motion to plasma heating and to acceleration of reflected particles to high energies.
These processes are closely related to the shock front structure. The paper
compares the structure of low-Mach number fast forward interplanetary shocks
registered by Wind and ACE with observations of bow shock crossings observed by
the Cluster, THEMIS, and Spektr-R spacecraft. Application of the high-time
resolution data facilitates further discussion on formation mechanisms of both types
of shocks.
