Book Description
“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 Description
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 Description
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.
