Abstract The National Solar Observatory/Kitt Peak synoptic rotation maps of the magnetic
field and of the equivalent width of the He i 1083 nm line are used to identify and measure …

Key drivers of solar weather and mid-term solar weather are reviewed by considering a
selection of relevant physics-and statistics-based scientific models as well as a selection of …

Анализ данных магнитной обсерватории ИЗМИРАН показал, что геомагнитные бури с
внезапным и постепенным началом образуют две независимые популяции, не …

The relationship between the solar polar magnetic field reversal and coronal hole evolution
is investigated for the time interval from 1996 to 2001. The distribution of coronal holes …

Abstract Two-dimensional (2D) solar coronal magnetogram is difficult to be measured
directly until now. From the previous knowledge, a general relation has been noticed that the …

An analysis of IZNIRAN magnetic observatory data indicated that geomagnetic storms with
sudden and gradual commencements form two independent populations with respect to the …

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

We developed an automated prediction technique for coronal holes using potential
magnetic field extrapolation in the solar corona to construct a database of coronal holes …

Filaments and coronal holes, two principal features observed in the solar corona, are
sources of space weather variations. Filament formation is closely associated with polarity …

It is shown that the contrast of coronal holes, just as their size, determines the velocity of the
solar wind streams. Fully calibrated EIT images of the Sun have been used. About 450 …
