Hα magnetic synoptic charts of the Sun are processed for 1915–1999 and the spherical
harmonics are calculated. It is shown that the polarity distribution of the magnetic field on Hα …

The data on solar magnetic fields since 1915 have been inferred from H-alpha filament
observations. We have used these data together with direct magnetographic observations to …

The structure and variations of open field regions (OFRs) are analyzed against the solar
cycle for the time interval of 1970–1996. The cycle of the large-scale magnetic field (LSMF) …

Монография посвящена современным представлениям о солнечной активности, её
цикличности, прогнозе будущих проявлений активности. Приведены основные …

To investigate the shape of the solar cycle, we have performed a wavelet analysis of the
large-scale magnetic field data for 1960–2000 for several latitudinal belts and have isolated …

The rotation characteristics of large-scale (global) magnetic fields (GMF) and their relation to
the activity of local fields (LMF) are studied over a long time interval (1915–1996). The main …

We develop a single‐fluid 2‐D analytical model of the axially symmetric thin heliospheric
current sheet (HCS) embedded into the heliospheric plasma sheet (HPS). A HCS‐HPS …

Various forecast techniques have been analyzed with reference to solar activity cycle 24.
Three prediction indices have been proposed: the intensity of the polar field, the mean field …

Observations of the large-scale solar magnetic field (synoptic maps) and measurements of
the magnetic field of the Sun as a star (the total magnetic field) are used to determine the …

Abstract Lockwood, Stamper, and Wild (1999) argued that the average strength of the
magnetic field of the Sun has doubled in the last 100 years. They used an analysis of the …
