Observations from the recent Whole Heliosphere Interval (WHI) solar minimum campaign
are compared to last cycle's Whole Sun Month (WSM) to demonstrate that sunspot numbers …

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 …

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 …

High-speed solar wind streams originating from large coronal holes reached a maximum in
2003 during the descending phase of solar cycle 23. At the same time, magnetic activity (as …

The behavior of a number of solar wind, radiation belt, auroral and geomagnetic parameters
is examined during the recent extended solar minimum and previous solar cycles, covering …

We study the development of strong geomagnetic storms due to coronal mass ejections in
near-Earth space. We compare the time evolution of geomagnetic disturbances with the time …

We study the modulation of galactic cosmic rays (GCR) due to high-speed streams (HSS)
identified in the solar wind. We compare the GCR modulation due to i) streams with different …

A complex catalogue of high speed streams produced by coronal holes and their effects in
the terrestrial magnetosphere–the so-called geomagnetic storms–for Solar Cycle 24 (2009 …

We present a catalog of high-speed streams, along with their solar sources for solar
cycleá23. We study their distribution during different years and different phases of solar …
