In order to evaluate how much Total Solar Irradiance (TSI) has influenced Northern
Hemisphere surface air temperature trends, it is important to have reliable estimates of both …

The Sun is a variable active-dynamo star, emitting radiation in all wavelengths and solar-
wind plasma to the interplanetary space. The Earth is immersed in this radiation and solar …

Solar magnetic activity is expressed via variations of sunspots and active regions varying on
different timescales. The most accepted is an 11-year period supposedly induced by the …

Recently discovered long-term oscillations of the solar background magnetic field
associated with double dynamo waves generated in inner and outer layers of the Sun …

Solar magnetic activity is expressed via variations of sunspots and active regions varying on
different timescales. The most accepted is an 11-year period supposedly induced by the …

Using full disc synoptic maps of solar background magnetic field captured from the Wilcox
Solar Observatory for 30 latitudinal bands for cycles 21–24, principal components (PCs) or …

Seventeen reconstructions of past solar activity, based on cosmogenic isotope and auroral
data, were analyzed for the time interval CE 1402–1850 covering three prolonged periods of …

Abstract Daily ephemeris of Sun-Earth distances in two millennia (600–2600) showed
significant decreases in February–June by up to 0.005 au in millennium M1 (600–1600) and …

We explore the links between the averaged sunspot numbers (SSN) and a modulus
summary curve (MSC) of two largest eigenvectors of the solar background magnetic field …

In 2007, the journal «Bulletin of the Crimean Astrophysical Observatory» published an
article of a Russian scientist and astrophysicist H. Abdussamatov «On long-term variations …
