Overview

Analysis of geomagnetic data identifies significant correlations and dynamics during magnetic storms in Georgia, indicating the importance of localized studies.

Key Points

  • This research aims to analyze geomagnetic field measurements during intense storms to understand the relationship between various solar and geomagnetic parameters.
  • Analyzed geomagnetic measurements from Dusheti Observatory during three storms in 2024.
  • Used cross-correlation, wavelet coherence, and detrended fluctuation analysis to assess data relationships.
  • Investigated dynamics between interplanetary magnetic field, solar wind plasma, and geomagnetic field H-component.
  • Identified significant correlations with distinct time lags of approximately 200 minutes.
  • Revealed complex solar wind-magnetosphere coupling dynamics through wavelet coherence analysis.
  • Observed increased coherence in plasma with a 12.5-hour time shift, linked to coronal mass ejection structure.
