In this paper, an operational Dst index prediction model is developed by combining empirical and Artificial Neural Network (ANN) models. ANN algorithms are widely used to predict space weather conditions. While they require a large amount of data for machine learning, large-scale geomagnetic storms have not occurred sufficiently the last 20 years, Advanced Composition Explorer (ACE) Deep Space Climate Observatory (DSCOVR) mission operation period. Conversely, models based on numerical...
Storm sudden commencements (SSCs) occur due to a rapid compression of the Earth's magnetic field. This is generally believed be caused by interplanetary (IP) shocks, but with exceptions. In this paper we explore possible causes SSCs other than IP shocks through statistical study geomagnetic storms using SYM-H data provided World Data Center for Geomagnetism - Kyoto and applying superposed epoch analysis simultaneous solar wind parameters obtained Advanced Composition Explorer (ACE)...
