Resumen:
The Cassini orbit insertion phase yielded a rich dataset from the
magnetometer instrument (MAG) which provided magnetic field measurements
in the solar wind, magnetosheath and magnetospheric regions of Saturn.
During the inbound and outbound pass of the insertion orbit, Cassini MAG
detected multiple bowshock and magnetopause crossings. We comment on the
structure and variability of these magnetic boundaries implied by the
data. We also study the properties of low frequency waves in Saturn's
upstream and magnetosheath regions. In particular, observations of
non-linear, low-frequency waves called "shocklets", and mirror-mode
waves are presented. Their properties, occurrence and origin are also
discussed.
