Asymmetry of Sunspot Distribution in Solar Cycles 12–24 and the Gnevyshev–Ohl Rule

Autor: Marta Tyasto, D. G. Baranov, E. S. Vernova, O. A. Danilova

Publikováno v: Geomagnetism and Aeronomy. 60:816-824

The nonaxisymmetric component of the sunspot distribution (longitudinal asymmetry) is considered based on the Greenwich–USAF/NOAA data for 1874–2016. Vector summation was used to estimate the value of longitudinal asymmetry. The asymmetry vector

Nonaxisymmetric Component of the Solar Photospheric Magnetic Field

Autor: O. A. Danilova, D. G. Baranov, E. S. Vernova, Marta Tyasto

Publikováno v: Geomagnetism and Aeronomy. 59:1029-1035

The longitudinal asymmetry of the photospheric magnetic field distribution is studied based on data from the Kitt Peak National Solar Observatory (synoptic maps for 1976–2016). Vector summation is used to weaken the effect of a stochastic component

Nonaxisymmetric Component of Solar Activity: the Vector of the Longitudinal Asymmetry

Autor: E. S. Vernova, M. I. Tyasto, D. G. Baranov, O. A. Danilova

Publikováno v: Solar Physics. 295

The vector representation of sunspots is used to study the nonaxisymmetric features of the solar activity distribution (sunspot data from Greenwich–USAF/NOAA, 1874–2016). Each sunspot is represented by a polar vector with modulus equal to the sun

Latitudinal Distribution of Photospheric Magnetic Fields of Different Magnitudes

Autor: M. I. Tyasto, D. G. Baranov, E. S. Vernova

Publikováno v: Solar Physics. 291:741-750

Photospheric magnetic fields are studied using synoptic maps from 1976 to 2003 produced at the National Solar Observatory, Kitt Peak (NSO/KP). Synoptic maps were averaged over the time interval of nearly three solar cycles (Solar Cycles 21-23). The c

Polarity imbalance of the photospheric magnetic field

Autor: O. A. Danilova, E. S. Vernova, M. I. Tyasto, D. G. Baranov

Polarity imbalance of the photospheric magnetic field was studied using synoptic maps of NSO Kitt Peak (1976-2016). Imbalance of positive and negative fluxes was considered for the fields with strength B>50 G in the sunspot zone (5 deg - 40 deg) and

Positive and Negative Photospheric Fields in Solar Cycles 21 - 24

Autor: D. G. Baranov, E. S. Vernova, Marta Tyasto, O. A. Danilova

Distribution of the positive and negative photospheric fields is studied on the base of synoptic maps of the photospheric magnetic field produced by the National Solar Observatory Kitt Peak (NSO Kitt Peak) for 1976-2016. In the analysis only the sign

Latitudinal profiles of the photospheric magnetic field for solar cycles 19-21

Autor: D. G. Baranov, Marta Tyasto, E. S. Vernova

For groups of photospheric magnetic fields differing in strength the time averaged synoptic maps were obtained on the basis of the National Solar Observatory Kitt Peak data (1976-2003). The latitudinal profiles of magnetic field fluxes were considere

Magnetic fields of photosphere and interplanetary space: Imbalance between positive and negative polarities

Autor: D. G. Baranov, Marta Tyasto, E. S. Vernova

Publikováno v: Geomagnetism and Aeronomy. 54:920-925

Photospheric magnetic fields are studied in this work on the basis of synoptic maps from the Kitt Peak Observatory (1976–2003) and WSO (1976–2012). The imbalance between positive and negative fluxes is considered for strong magnetic fields in the
