  Polars are highly magnetic cataclysmic variables which have been long
observed to have both high and low brightness states. The duration of these
states has been previously seen to vary from a number of days up to years.
Despite this; these states and their physical origin has not been explained in
a consistent manner. We present observations of the shortest duration states of
a number of Polars observed by ZTF and TESS. This has allowed us to determine
that short duration states are a relatively common feature across the
population of Polars. Furthermore we have been able to generalise the model of
star spot migration to explain both short lived high and low states in Polars
by incorporating the interaction between the magnetic field of the white dwarf
and that of the star spots.
