Abstract
- Sunspot is known as the area with the highest solar magnetic activity and has the coolest region compared to its surrounding. It is also influenced by sunspot complexity and magnetic field strength. The huge explosion of solar energetic particles in the interplanetary space due to Coronal Mass Ejections (CMEs) and solar flares is believed due to instability of magnetic field and complexity magnetic field in the sunspot. Due to these events, the intense solar radio emission also known as solar radio bursts were released to the Earth. Delta (δ) sunspot is one of the largest magnetic classification of sunspot and seen mostly released solar flares and CMEs, however, Beta Gamma (βγ) sunspot has the highest formation from 2012 to 2016 compared to other type of bursts and has tendency to produce solar flares and CMEs. The data were collected using Space Weather Website (SWPC) and NOAA, e-CALLISTO network and LPDA. The data were collected within 5 years (2012-2016) and reveals βγ sunspot has (349 counts) (62.77%), followed by βγσ sunspot (160 counts) (28.78%), δ sunspot (39 counts) (7.01%) and βγ sunspot (8 counts) (1.44%), thus, highlights the highest type of magnetic classification occurred on Active Region (AR) was βγ sunspot. Highest formation of βγ sunspot illustrated the complexity of the βγ sunspot due instability of magnetic field inside AR and has tendency to produce flares and CMEs compared to other types of magnetic classifications. Furthermore, βγ sunspot demonstrated a tendency to generate Type II burst, Type III burst, Type IV burst and combination of bursts which we classified as selected events. This finding proved that Type IV burst has the highest formation of burst followed by Type III burst, Type II burst and selected events. Type IV burst has counted for 161 counts (56.29%), Type III burst (100 counts) (34.96%), Type II burst (14 counts) (4.9%) and selected events (11 days) (3.85%). The type of bursts was determined by the range frequency of burst and the duration of burst. The different types of bursts have different ranges of frequency and duration of bursts. Type IV burst displayed the highest formation due its associated phenomena mostly was sunspot where the location of events occurred, followed by Type III burst (solar flares), Type II burst (CMEs) and selected events. These findings were important in solar activity study as prediction and forecast for Solar Cycle 25. These significant findings manage the process of shutting down the system from breakdown due to high energetic particles being released from solar flares and CMES. This prediction can shut down the system in satellites and prevent the power grid and telecommunication system from breakdown.
