Book Synopsis Observing the Sun by : Jamey L. Jenkins
Download or read book Observing the Sun written by Jamey L. Jenkins and published by Springer Science & Business Media. This book was released on 2013-07-19 with total page 255 pages. Available in PDF, EPUB and Kindle. Book excerpt: “Observing the Sun” is for amateur astronomers at all three levels: beginning, intermediate, and advanced. The beginning observer is often trying to find a niche or define a specific interest in his hobby, and the content of this book will spark that interest in solar observing because of the focus on the dynamics of the Sun. Intermediate and advanced observers will find the book invaluable in identifying features (through photos, charts, diagrams) in a logical, orderly fashion and then guiding the observer to interpret the observations. Because the Sun is a dynamic celestial body in constant flux, astronomers rarely know for certain what awaits them at the eyepiece. All features of the Sun are transient and sometimes rather fleeting. Given the number of features and the complex life cycles of some, it can be a challenging hobby. “Observing the Sun” provides essential illustrations, charts, and diagrams that depict the forms and life cycles of the numerous features visible on the Sun.

Book Synopsis Solar Observations at 8.6-mm Wavelength by : Paul M. Kalaghan
Download or read book Solar Observations at 8.6-mm Wavelength written by Paul M. Kalaghan and published by . This book was released on 1970 with total page 58 pages. Available in PDF, EPUB and Kindle. Book excerpt: The advent of manned space flights has focused attention on the biological threat posed by solar proton flares. In an effort to close one of the gaps in the observation of the solar spectrum, AFCRL has initiated a high resolution millimeter wavelength solar observation program. This report covers the observational approach and initial findings of this program based upon observations from May to December 1968. The equipment and procedures used to produce spectroheliograms at 8.6 mm, using the AFCRL 29-ft Millimeter Wave Antenna, are described. The quiet sun at 8.6 mm appeared to have a brightness temperature of 8400 plus or minus 600 K blackbody and a 'radio diameter' 3 percent greater than the optical disk. The presence of active regions during this period was characterized by localized enhanced regions exhibiting temperature increases from 1 to 28 percent of the quiet sun level. The enhancement and the positions of these regions have been compared with 9.1-cm radio data and various other optical data. The locations of the 8.6-mm enhanced regions are contained within calcium plages. All proton events observed originated only in highly enhanced (Class III) regions. Further observations are in progress to increase the sample size of observed proton events to further refine the possibility of prediction of these events. (Author).

Book Synopsis The Sun Recorded Through History by : J.M. Vaquero
Download or read book The Sun Recorded Through History written by J.M. Vaquero and published by Springer Science & Business Media. This book was released on 2009-04-21 with total page 395 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Sun is nowadays observed using di?erent techniques that provide an almost instantaneous 3-D map of its structure. Of particular interest is the studyofthevariabilityinthesolaroutputproducedbythedissipationofm- netic energy on di?erent spatial and temporal scales – the so-called magnetic activity. The 11-year cycle is the main feature describing this phenomenon. Apart from its intrinsic scienti?c interest, this topic is worth studying because of the interaction of such processes with the terrestrial environment. A ?eet of space and ground-based observatories are currently monitoring the behaviour of our star on a daily basis. However, solar activity varies not only on this decadal time-scale, as has been attested mainly through two methods: (a) records of the number of sunspots observed on the solar surface from 1610, and (b) the records of 14 10 cosmogenic isotopes, such as Cand Be, measured in tree-rings and i- cores, respectively. The study of the long-term behaviour of solar activity may be comp- mented by the study of historical accounts describing phenomena directly or indirectly related to solar activity. Numerous scienti?c and non-scienti?c d- uments have reported these events and we can make use of them as a proxy of solar activity in past times.

Book Synopsis The Sun and How to Observe It by : Jamey L. Jenkins
Download or read book The Sun and How to Observe It written by Jamey L. Jenkins and published by Springer Science & Business Media. This book was released on 2009-03-01 with total page 206 pages. Available in PDF, EPUB and Kindle. Book excerpt: In Part 1, the book describes the very latest thinking on solar physics in (mostly non-mathematical) detail, incorporating the latest results from research concerning the structure and behaviour of the Sun. There is particular emphasis on the surface features visible from the Earth, and how these are the result of the extraordinary processes that are taking place within the Sun. In Part 2, the book details the techniques for observing and imaging the Sun with commercially-available equipment. The many recent advances in optical equipment now allow amateur astronomers to observe phenomena that until recently could only be seen with the extremely expensive equipment available at universities and research observatories – notably H-alpha and Calcium-K telescopes. This is a completely up-to-date solar observing book, while providing the science background necessary for an understanding of the observations with the latest equipment. It also features the most complete solar observing and imaging guide available.
Book Synopsis Early Solar Physics by : A. J. Meadows
Download or read book Early Solar Physics written by A. J. Meadows and published by Elsevier. This book was released on 2016-01-21 with total page 325 pages. Available in PDF, EPUB and Kindle. Book excerpt: Early Solar Physics reviews developments in solar physics, particularly the advent of solar spectroscopy and the discovery of relationships between the various layers of the solar atmosphere and between the different forms of solar activity. Topics covered include solar observations during 1843; chemical analysis of the solar atmosphere; the spectrum of a solar prominence; and the solar eclipse of December 12, 1871. Spectroscopic observations of the sun are also presented. This book is comprised of 30 chapters and begins with an overview of ideas about the sun in the mid-nineteenth century, followed by a summary of progress in astronomy between 1850 and 1900, including observations of the solar surface, sunspots, and solar flares. The founding of the Mount Wilson Solar Observatory is cited. Observations of the sun made with solar spectroscopy are presented, including those of the sun's temperature. The results of a detailed examination of spectra photographed during the solar eclipse of January 22, 1898 are also discussed. The final chapter examines the magnetic properties of the earth and sun. This monograph will be a useful resource for astronomers, astrophysicists, and those interested in discovering many aspects of the sun.

Book Synopsis Polarization Spectra of Centimeter-wavelength Solar Bursts Using Whole-sun Observations by : Donald A. Guidice
Download or read book Polarization Spectra of Centimeter-wavelength Solar Bursts Using Whole-sun Observations written by Donald A. Guidice and published by . This book was released on 1976 with total page 42 pages. Available in PDF, EPUB and Kindle. Book excerpt: The physics of microwave-burst emission is briefly examined to give the rationale for investigating polarization spectra. The instruments used to carry out the 9.4 GHz and 7 GHz circular-polarization measurements and the 5 GHz Stokes-parameter measurements are described. A survey of the August 1972 to December 1973 period produced a table of 45 bursts, from which some limited results were obtained. About 75 to 80 percent of all bursts are circularly polarized, with varying polarization over the 5 to 9.4 GHz range. For most bursts where the circular polarization pc increases toward the upper or lower end of the 5 to 9.4 GHz range, the total intensity I also increases in that direction. The few bursts having a pc sense reversal in the 5 to 9.4 GHz range also have a spectral maximum of I at roughly the same frequency. Some simplified explanations of the results are presented.

Book Synopsis Observing the Sun by : Peter O. Taylor
Download or read book Observing the Sun written by Peter O. Taylor and published by Cambridge University Press. This book was released on 1991-11-21 with total page 180 pages. Available in PDF, EPUB and Kindle. Book excerpt: Observing the Sun is one of the most interesting and rewarding facets of astronomy to which amateurs can contribute. Few areas of science offer as many opportunities to contribute meaningful data. It is the one branch of astronomy that requires only modest equipment and can be pursued during the day. Peter Taylor is a keen and highly experienced observer of the Sun. In this book he explains in a clear and practical way everything that a telescope user needs to know in order to make solar observations. The author draws on his many years of personal experience as a contributor to the Solar Division of the American Association of Variable Star Observers and to the American Sunspot Program. The book deals with the following topics: historical background, choice of equipment for the safe conduct of solar observations, observations of sunspots, and reporting observations. New techniques, such as electronic recording and the operations of radio telescopes, are included. The level of presentation is understandable to anyone with basic astronomical knowledge and some experience in handling a small telescope.
