The shift of the heliospheric current sheet (HCS) can be judged by the correlation between polarities of the interplanetary magnetic field (IMF) observed near the Earth. Here the IMF polarities which were reconstructed from the geomagnetic data of th

The paper discusses the results of the forecast of solar wind parameters at a distance of 1 AU made according to observations made by the STOP telescope magnetograph during 2014–2015. The Wang–Sheeley–Arge (WSA) empirical model is used to recon

One of the most enigmatic features of the solar history is the Maunder minimum (1645–1715). We compare the scatter of amplitudes of the 11-year cycles, according to the new Sunspot Number and Sunspot Group series version 2.0, along with scenario of

The 22-year cycle in the solar activity known as the even-odd effect is compared with the odd-even order. We find that the grouping into the even-odd pairs is not preferable in comparison to that of odd-even ones. We argue that due to existed relatio

The sunspot numbers and polar faculae are analyzed to demonstrate that the current solar activity is close to the Grand minimum. Notably protracted Cycle 23 is found to be similar to the cycles on the eve of the Dalton and Gleissberg–Gnevyshev mini

The spatiotemporal organization of sunspots in the form of activity impulses (according to Gnevyshev’s terminology) is considered as a source of poleward magnetic surges of new polarity. Polar fields in the northern and southern hemispheres have be

[1] The interplanetary magnetic field (IMF) is the magnetic field of the Sun stretched out by the solar wind. The polarity of the IMF is either positive or negative according to the polarity of the original solar magnetic field. The equivalent ionosp

This paper describes a new method for reconstructing the polarity of the interplanetary magnetic field. The technique is based on the Svalgaard-Mansurov effect. We ause geomagnetic data of high-latitude stations with a long observation period, includ

The poleward magnetic field streams on time-latitude diagram of the photospheric magnetic field of the Sun during 1975–2011 (Kitt Peak NSO, SOLIS NSO, SOHO MDI data) are modeled. We performed simulations in terms of probability density function and

Gnevyshev’s hypothesis of time space organization of sunspot activity over the solar surface like impulses is considered. Using numerical simulation it was shown that complex solar cycle shape can be explained by distribution of impulses in the nor
