Download or read book Solar Coronal White Light Fe X Fe XIV and Ca XV Observations During 1984 written by D. G. Sime and published by . This book was released on 1985 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synoptic observations of the solar corona in white light and in three emission lines (Calcium XV at 5964 A, Iron XIV at 5303 A, and Iron X at 6374 A) were carried out. The observations provide a record of the distribution of the density of the corona as well as the distribution and brightness of the hotter regions of the corona over the year. We present these data in the form of synoptic maps for each rotation during the year for the purpose of providing a context for the investigations which are to take place during the Joint Study of Coronal and Prominence Plasmas. In this way, we propose both to describe the data coverage achieved and summarize the large scale properties of the corona in this late descending phase of the solar cycle. Keywords: Solar corona; Solar emission lines; Solar observations.

Book excerpt: The third COSPAR Colloquium entitled Solar Wind Seven was held in Goslar, Germany in September 1991. Twenty-two countries were represented by scientists, many of whom are leading experts in the area of heliospheric physics. The Proceedings reflect current research on solar wind and particularly emphasizes the source regions. The main topics covered encompass Coronal Heating and Solar Wind Acceleration; Large-Scale Structure of the Interplanetary Medium; Minor Ions, Neutrals and Cosmic Rays in the Heliosphere; Kinetic Physics, Waves and Turbulence and finally Heliospheric Dynamic Phenomena.

This book was released on 2012-11-30 with total page 508 pages. Available in PDF, EPUB and Kindle. Book excerpt: Astronomy is the science of everything – with the exception of the Earth and everything on it and inside. Astronomy has a rich heritage dating back to the myths and legends of antiquity and the course of civilization has been greatly affected by mankind’s interpretation of what they saw in the starry sky and experienced through seasonal changes associated with the Sun and Moon. Early astronomy is associated with the definition of calendars which were needed to predict the dates of such as religious festivals and the numbers of months. A gradual shift of emphasis from astronomy to its sister, astrophysics, which took place through the 19th century, is generally attributed to the measurement of reliable stellar distances and the development of spectroscopy as a tool for understanding the physical nature of stars. Many paradigms in astronomy and its many subfields are continuously being shaken. New insights in the intricacy and elegance of the cosmos are steadily being obtained. Every few decennia, our concepts of the Universe are challenged and substantially modified. The reasons for this are the continuous development of new observing techniques and instruments for observatories both ground-based and in space, in addition to considerable progress in mathematics and physics, including computational ability. Our Universe harbors numerous phenomena and processes representing conditions that cannot be duplicated in terrestrial laboratories. Astronomy therefore frequently leads to fundamentally new insight and knowledge far beyond astronomy itself. Last but not least, it represents a first inspiring introduction to natural science, especially among young people, which is an extra motivation to many scientists to contribute to the Astronomy and Astrophysics Theme of this Encyclopedia. The book on Astronomy and Astrophysics with contributions from distinguished experts in the field, represents a first inspiring introduction to natural science, especially among young people, which is an extra motivation to many scientists to contribute to the Astronomy and Astrophysics Theme of this Encyclopedia. The first chapter which treats the development of astronomy and astrophysics in a historical perspective is followed by an account of the impact of astronomy on human culture and civilization. Observational astronomy is facing a number of environmental challenges. The nature and complexity of these and how the associated problems are met and overcome are described in the third article. Various aspects of our solar system are covered by authoritative articles on the Sun, planets including their satellites and smaller bodies, plus a review of the laws of motions and orbits of celestial bodies. The detection and studies of exo-solar planetary systems is rapidly developing field in astronomy which is treated in a separate chapter. Then follow fascinating up-to-date overviews on stars describing their formation, structure and life cycles. Stars are the building blocks of larger cosmic entities leading to the enigmatic galaxies composed of billions of stars, and gradually to clusters of galaxies. The final chapters cover the origin and evolution of galaxies and the large-scale structure of the Universe, including dark matter and dark energy which are among the most fascinating problems of physics today. These two volumes are aimed at the following five major target audiences: University and College students Educators, Professional practitioners, Research personnel and Policy analysts, managers, and decision makers and NGOs.

Download or read book The Fe XIV Solar Corona at 5303 Angstroms An Atlas of Synoptic Charts from the Sacramento Peak Coronal Photometer May 1973 December 1985 written by R. C. Altrock and published by . This book was released on 1987 with total page 168 pages. Available in PDF, EPUB and Kindle. Book excerpt: Synoptic photoelectric observations of the solar corona in the emission from the green line (5303A) of Fe XIV were begun at the Sacramento Peak Observatory in June 1973 and continue to the present. The observations made during this program provide a record of the distribution and brightness of the hotter regions of the corona (1,800,000 K) over an entire solar cycle. As such, the green line data may provide a link between the active regions of the chromosphere and the large scale structure of the corona. In order to allow comparison of these data with other observations of the sun and corona, we present here an atlas of the green line measurements in the same format as that used to display the white light coronal structure recorded by the High Altitude Observatory's K-coronameters on Mauna Loa, in previously published atlases. It is our intent that this atlas be brought up to date periodically as the observations permit.

Available in PDF, EPUB and Kindle. Book excerpt: The International Heliospheric Study is a program sponsored by COSPAR that exploits the unique scientific opportunities presented by the continuing operation of the four Pioneer and Voyager spacecraft which are all in or beyond the outer solar system. The heliosphere is the region of space surrounding the sun which is dominated by the solar wind and from which the local interstellar plasma and magnetic field are excluded. The multispacecraft studies which form the basis of the IHS encompass the structure and dynamics of the solar wind and its interaction with the interstellar medium including those components, neutral gas and galactic cosmic rays, which are able to penetrate into the heliosphere.
