Summary: | Solar activity produces several major events that affect the surrounding
environment including Earth, one of which is a flare event. Most of the
flares occur in active areas where there are many sunspots which tend
to appear in groups. Sunspot groups in general have evolved both in
terms of magnetic configuration, sunspot area, and the environment
around the main sunspot.
Flares may have a direct impact on Earth within only minutes after the
flare occurs. The effect of these flares could be informs of damages to
Earth and space-based technologies, such as satellites and radio. The
great impact of these flares has made scientists conduct research to
predict the occurrence of flares as an effort to prepare strategic steps to
reduce the impact of flares on Earth.
This research was conducted to study the correlation between sunspot
features and their environment with the possibility of flares occurring
and the effects of flares on the sunspot environment. The study was
conducted by utilizing HMI Continuum imagery data from the SDO
satellite and data compiled on solarmonitor.org. The sunspot data that
is the focus of this research consist of at least two sunspots for each class
of flares and those that do not produce flares around the solar equator.
This research is expected to provide insight into the pattern of
environmental evolution of sunspots and their relation to the probability
of flares. Environmental analysis of sunspots with the probability of
flares is carried out by taking into account sunspot features which
include changes in sunspot morphology, number of spots, and the size of
the sunspot area.
The results showed that a measurable evolution of sunspot features was
seen in the form of an increase in activity by looking at the appearance
of the sunspot along with a flare event. Likewise, after a flare event, the
features that are the object of research show decreased activity.
However, in contrast to sunspots which do not produce flares, the pattern
of environmental evolution tends to decreasing activity as the sunspot
ages. |
