This research provides an analysis of extreme events in the solar wind and in
the magnetosphere due to disturbances of the solar wind. Extreme value theory
has been applied to a 20 year data set from the Advanced Composition Explorer
(ACE) spacecraft for the period 1998-2017. The solar proton speed, solar proton
temperature, solar proton density and magnetic field have been analyzed to
characterize extreme events in the solar wind. The solar wind electric field,
vB$_{z}$ has been analyzed to characterize the impact from extreme disturbances
in the solar wind to the magnetosphere. These extreme values were estimated for
one-in-40 and one-in-80 years events, which represent two and four times the
range of the original data set. The estimated values were verified by
comparison with measured values of extreme events recorded in previous years.
Finally, our research also suggests the presence of an upper boundary in the
magnitudes under study.
