Available in PDF, EPUB and Kindle. Book excerpt: The devotion of an IA U symposium entirely to the topic of chromo spheric fine structure at a time when models of the spherically symmetric chromosphere are still evolving constitutes a valid recognition of the growing feeling among solar astron omers that the chromosphere cannot be understood independently of its discrete structural features. Network structure, which seemingly borders the photospheric supergranule cells, persists intact throughout the chromosphere and most of the chromosphere-corona transition region. The network is the locus of the bright coarse mottles, and the spicule bushes and is the terminus for one end of the quiet chromo spheric fibrils as well. Additionally, it is the locus of most of the magnetic flux of the quiet chromosphere. It is not surprising, therefore, that current studies of the chromosphere tend to center around efforts to better describe the network phenom ena and to ascertain the physical properties of the network features. Clearly, the supergranule cells and associated network structures constitute a fundamental and singularly important feature of solar structure in the boundary layers. Just as it is now clear that much of the chromo spheric fine structure is associated with the network bordering supergranule cells, it seems equally clear that structural features are almost universally associated with both fluid flow and magnetic geometry. Indeed, many observers claim that the brightness features faithfully map the mag netic lines offorce while still others claim that associated with each class of brightness feature there is a more or less unique fluid flow.

Book excerpt: The sun was observed in the H-alpha line and around it in the quiet regions and in the active regions. Preliminary results were obtained concerning the life-times and changes of the fine structures in the quiet regions and the active regions, the bright streaks and the identification of the H-alpha plages and the photospheris faculae.

Available in PDF, EPUB and Kindle. Book excerpt: The solar chromosphere at the limb and also on the disk is studied with the purpose of ascertaining its fine structure and the relation between the spicules and the dark and bright fine mottles on the disk. High resolution time-lapse photography of the sun are made using a 150 mm Coude' refractor in conjunction with the 1/2 Angstrom band-width Zeiss H-alpha filter set at different positions on the profile of the line. Good data of the chromosphere at the limb at different wavelength settings and also on the disk at plus or minus 0.75 Angstrom from the line center are obtained. The data contain information on the fine structures at the solar limb and also about the time development of the dark and bright fine mottles at plus or minus 0.75 Angstrom from the line center. Reduction of the data is in progress. (Author).

This book was released on 2017-10-12 with total page 500 pages. Available in PDF, EPUB and Kindle. Book excerpt: Solar activity has become of increasing importance in our modern society, as many aspects of today's technology could be affected by eruptive phenomena associated with solar magnetic variability. State of the art solar instrumentation is revealing the dynamics of the Sun with unprecedented temporal and spatial resolutions. This volume includes recent results in solar physics research presented at the IAU Symposium 327, the first IAU symposium held in Colombia, in the historical city of Cartagena de Indias, one of the oldest in the Americas. Its main scientific goal was to discuss recent results on the processes shaping the structure of the solar atmosphere and driving plasma eruptions and explosive events in our star. Researchers in both theory and observation, who study structure and activity in the solar atmosphere, discuss a wide range of topics in the field.
