EARLY DIAGNOSTICS OF GEOMAGNETIC STORMS BASED ON OBSERVATIONS OF SPACE MONITORING SYSTEMS
Journal Title: Solar-Terrestrial Physics - Year 2019, Vol 5, Issue 1
Abstract
We address the problem of early diagnostics of geomagnetic storms based on the use of models of coordinates of movements of centers of solar coronal mass ejections (CME) and observations of their angular positions obtained from space monitoring systems. We propose a method for early diagnostics of geomagnetic storms, introduce a function to predict the distance between Earth and CME centers, and establish a decision-making procedure. We give an example of calculating the distance prediction function and implement the diagnostic decision-making procedure based on coordinate models and model observations of angular positions of CME centers. We determine the efficiency of the decision-making procedure for the algorithm for early diagnostics of geomagnetic storms.
