Abstract : A study was conducted of the correspondence of photospheric magnetic fields with structures and transient phenomena observed in the chromosphere. The primary data used were isogauss maps constructed from the Mt. Wilson daily, full disk magnetograms for the period 1959 through 1962, and three fine-scan magnetograms made on 6 July 1965.

Magnetic field of the solar wind
Solar Physics, 1976Relationship between the geoefficiency of the solar flares as well as of the active regions passing the central meridian of the Sun and the configuration of the large scale solar magnetic field is studied. It is shown that if the tangential component of the large scale magnetic field at the active region or at the flare region is directed southwards ...

The proximity of the Sun allows us to make detailed measurements on the properties of solar magnetic fields. The long term systematic changes in the solar magnetic field pattern indicate a global origin. A global dynamo can be sustained by the interaction of solar convection with solar rotation.

Evolution of the solar magnetic field
Icarus, 1965Abstract The possibility is demonstrated that the solar magnetic field, rather than being of internal origin, may have originated, during the process of the Sun's formation, from a galactic magnetic field which pervaded the interstellar gas out of which the Sun condensed The magnetic field in the condensing gas cloud is maintained at approximately ...

The Solar Magnetic Field and the Solar Activity
1965The Sun has a mass of 2 × 1033 g, a radius of 7 × 1010 cm, a luminosity of 3.6 × 1033 ergs sec-1. The internal structure of the Sun is determined by the equation of hydrostatic equilibrium, the equation of transfer of energy and the equation of energy generation by thermonuclear reactions.

Geomagnetism and Aeronomy, 2013
The solar polar magnetic field has attracted the attention of researchers since the polar magnetic field reversal was revealed in the middle of the last century (Babcock and Livingston, 1958). The polar magnetic field has regularly reversed because the magnetic flux is transported from the sunspot formation zone owing to differential rotation ...

Magnetic Fields and Solar Activities
Astrophysics and Space Science, 2006We discuss the study of solar magnetic fields based on the photospheric vector magnetograms of solar active regions which were obtained at Huairou Solar Observing Station near Beijing in the period of 22nd and 23th solar cycles. The measurements of the chromospheric magnetic field and the spatial configuration of the field at the lower solar atmosphere

Magnetic Fields in the Solar Corona
Nature, 1967IT has been proposed by Sturrock1 that the frequency splitting sometimes observed in type II solar radio bursts may be caused by excitation of plasma oscillations by supra-thermal electrons moving through the solar corona in the presence of density irregularities and a weak magnetic field. He showed that in these circumstances electromagnetic waves may

Solar Magnetic Fields and Convection
1976We review the primordial field theory of solar magnetic fields (Papers I–VI) whose three main features are, first, a permanent dipole-like magnetic field, second a mainly toroidal field formed by shearing and rolling into individual, helically twisted ropes as suggested by Babcock, and third a mechanism for reversing the toroidal field.
