A Comparison of Velocities Among Different Solar Active Regions: A Time-Based Analysis

This study investigates the varying velocities of different solar active regions depending on their latitude to enhance our understanding of solar dynamics and improve space weather prediction. Utilising data from NASA’s Solar Dynamics Observatory taken at 94 Å to 4500 Å, I obtained distinct average velocities for 3 solar active regions: the equator feature exhibited an average velocity of 5862.73 km/h, while the North Pole Feature averaged 5881.20 km/h and the South Pole Feature at 7099.08 km/h. Due to the plasma composition of the sun, rotational speeds vary and are the highest at the equator. My findings mostly align with existing research. However, the short observational period; low-resolution data and positioning errors of the SDO contributed to slight measurement errors.
