Features of Geophysical Manifestations of Solar Activity in August 2018 According to Muon Hodoscope URAGAN Data

Variations of the muon flux of cosmic rays (using data from the URAGAN muon hodoscope) and perturbations of the Earth’s magnetic field (OMNI database) were analyzed for August 2018, when there were almost no active regions on the solar disk and the number of sunspots was close to zero. The Kp and Ds...

Description
Summary:Variations of the muon flux of cosmic rays (using data from the URAGAN muon hodoscope) and perturbations of the Earth’s magnetic field (OMNI database) were analyzed for August 2018, when there were almost no active regions on the solar disk and the number of sunspots was close to zero. The Kp and Dst geoefficiency coefficients were found to be elevated when the Earth entered the region of fast solar wind from coronal holes. Analysis of the non-stationarity factor C ( t ) for the muon count time series N µ ( t ) shows that there are always elevated C ( t ) values that are ahead of the fast solar wind from coronal holes by (1–3) days. A predictor was also found in the sequence of values C ( t ) which is 1-day ahead of the geo-effective storm (SSC-power G 3) of the solar CME eruption on August 20.
