The Sun is the major source of heat and light in our solar system. The solar
cycle is the 11-year cycle of solar activity that can be determined by the rise
and fall in the numbers and surface area of sunspots...Solar activity is
associated with several factors including radio flux, solar irradiance,
magnetic field, solar flares, coronal mass ejections, and solar cycles. This
study attempts to determine the Sun's activity specifically for the coronal
mass ejection, its trend during solar cycle 23, and its apparent difference. A
time series analysis was used to measure the CME data for larger cases and to
see the apparent difference and trends of the CMEs. The result shows that a
decreasing trend of coronal mass ejection from the year 1996 to 2016. It is
therefore concluded that the coronal mass ejection data are normally
distributed while coronal mass ejections are distributed and curved normally as
fluctuation was found in the intensity of the disturbed storm time index as the
number of great geomagnetic storms undeniably increased in the ascending and
descending phases of the cycle. This reveals that eventhough the Sun has cycles
and trends, it shows its inherent characteristics. The Sun still possess
getting more dynamic through time which showcases through the limited
parameters involved in this study.(read more)
