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.
