Interplanetary coronal mass ejections (ICMEs) that accompany solar flares are associated with the occurrence of severe geomagnetic storms. The goal of this research is to examine an intense geomagnetic storm on March 24th, 2023 with a symmetric disturbances index (SYM/H) of-200 nT and evaluate the CMEs, solar flares, and solar wind conditions associated with the storm. Furthermore, the strong storm associated with CMEs and solar flares has been examined using a low-latitude ground geomagnetic field (H-component) at TRE station. Data suggests that the two halo types of CMEs that occurred on March 20th, 2023, may have triggered severe geomagnetic activity. The occurrence of an intense geomagnetic storm on March 24th, 2023, is expected to be independent of the speed parameter of CME events (Vcme<2000kms-1). This research provides more insight into the potential for space weather hazards that could disrupt space ground in frastructure systems. © 2024, IEICES/Kyushu University. All rights reserved.
