This study investigates whether substorm onset locations on the Sun exhibit specific patterns by analyzing its source region-active regions (ARs), quiet sun (QS), and coronal holes (CH)-and their corresponding solar wind properties using statistical analysis. Matching event times were found using SuperMAG substorm, ACE, and WSA data. We analyzed geomagnetic indices (AE, AU, and AL) and solar wind variability, including Bz paths in magnetic field components, velocity, and density. Preliminary ...
