In the Sun, solar activities increase and decrease in
11-year cycles. Solar events and processes can lead to
the ejection of plasma material into space, and the
ejections of substantial mass from one region are
referred to as coronal mass ejections (CMEs). When
these mass ejections move through space and reach
Earth, they affect the Earth's magnetic field, causing
significant disturbances known as geomagnetic storms.
If there are two consecutive CMEs from the Sun and
they merge before reaching Earth, it becomes a
cannibal mass ejection. It impacts Earth as a plasma
with different densities and velocities than a typical
ejection. In this study, a multiple linear regression
model was created to explain the disturbance in the
Earth's magnetic field due to a cannibal mass ejection
occurring during the 25th solar cycle, which is the
current solar cycle. The independent variables in the
model are the speed of the cannibal mass ejection in
space and the proton density, while the dependent
variable is the Dst (Disturbance Storm Time) index,
which indicates the amount of disturbance in the
magnetic field. The main goal is to understand the
primary factors of geomagnetic storms through data
science since these storms can pose significant risks to
satellites, space missions, and life on Earth. The results
of the regression model are compared to the
consistency of astrophysical processes to discuss the
reality of storm analysis.
