Corotating interaction regions (CIRs) are structures formed when high‐speed solar wind
streams overtake slow solar wind streams as they propagate outward. These structures …

We study the Forbush decreases in cosmic-ray intensity from January 2008 to December
2013, covering the minimum between Solar Cycles 23 and 24 and the ascending phase of …

In this paper we provide significant evidence that the sun is a principal agent provoking
seismic activity. In particular the aim of the studies presented is to examine the possible …

In this study the response of ionospheric F-region to 18–21 September 2014, 19–24 January
2016, and 07–10 March 2016 CIR-driven storms in the equatorial and low-latitude region of …

We assess the contributions of various types of solar wind structures (transients, coronal
hole high-speed streams (HSS), and slow-speed wind) to hourly average auroral electron …

In this paper, we present the responses of the ionospheric total electron content (TEC) to
coronal mass ejection (CME)‐and corotating interaction region (CIR)‐driven storms using …

An updated catalog is created of 303 well-defined high-speed solar wind streams that
occurred in the time period 2009–2016. These streams are identified from solar and …

High-speed solar wind streams (HSSWSs) are ejected from the Sun and travel into the
interplanetary space. Because of their high speed, they carry out energetic particles such as …

We show that the enhancements in both the upper limiting rigidity of the cosmic ray solar
diurnal variation and the geomagnetic activity during the decline of solar activity are related …

Spectral analysis of neutron monitors and muon telescope daily averages counts shows a
significant higher harmonic (∼ 9 day) of the 27 day variation of galactic cosmic rays (CRs) …
