Journal of Physics: Conference Series, 2016•iopscience.iop.orgWe suggest the new approach that could be used in the task of geomagnetic indexes
forecasting. This approach based on the topological structure of the time series. The hourly
data of different geomagnetic indexes were analyzed. We split the whole series to the calm
parts, and geomagnetic storm preceding parts and find that the main measure of the
topological structure of the series which called topological persistence differ significantly
between these two groups.

Abstract
We suggest the new approach that could be used in the task of geomagnetic indexes forecasting. This approach based on the topological structure of the time series. The hourly data of different geomagnetic indexes were analyzed. We split the whole series to the calm parts, and geomagnetic storm preceding parts and find that the main measure of the topological structure of the series which called topological persistence differ significantly between these two groups.
