The magnetic field of the Sun is the underlying cause of the many diverse phenomena
combined under the heading of solar activity. Here we describe the magnetic field as it …

Historic geomagnetic activity observations have been used to reveal centennial variations in
the open solar flux and the near-Earth heliospheric conditions (the interplanetary magnetic …

The Sun continually ejects matter into space, blowing a huge bubble of supersonic plasma.
This solar wind bathes the whole solar system and shapes all planetary environments. The …

We have studied long-term variations of galactic cosmic-ray (GCR) intensity in relation to the
sunspot number (SSN) during the most recent solar cycles. This study analyses the time lag …

The global survey method (GSM) technique unites simultaneous ground-level observations
of cosmic rays in different locations and allows us to obtain the main characteristics of …

Solar magnetic activity drives the dominant 11-year cyclic variability of different space
environmental indices, but they can be delayed with respect to the original variations due to …

During the last solar cycle the Earth's cloud cover underwent a modulation in phase with the
cosmic ray flux. Assuming that there is a causal relationship between the two, it is expected …

The open solar magnetic flux has been recently reconstructed by Solanki et al.[2000, 2002]
for the last 400 years from sunspot data. Using this reconstructed magnetic flux as an input …

One of the variants of the global survey method developed and used for many years at the
Institute of Terrestrial Magnetism, Ionosphere, and Radio Wave Propagation of the Russian …

Production of cosmogenic nuclides (CNs) in geologic material is a function of the cosmic-ray
flux at the Earth's surface, which in turn is a function of the intensity and orientation of the …
