Available in PDF, EPUB and Kindle. Book excerpt: The sun has a dominant influence on the terrestrial environment, an environment which affects many phases of direct military interests such as the upper atmosphere, communications, satellite operations, weather, etc. The results obtained add to the interpretation of the solar terrestrial relationships that may add to their predictability. Superposed epoch studies of the daily sunspot numbers (Rz) show a different behavior when selected for daily sums of geomagnetic activity (SKp) of 45 up to 56 than for higher or lower values of SKp. (Author Modified Abstract).

Available in PDF, EPUB and Kindle. Book excerpt: Data of the geomagnetic index A sub p from 1932 to 1973 were used to determine the conditional probabilities for the occurrence of certain values of that index. The range of values was divided into three categories that approximately correspond to quiet, moderate, and disturbed levels of geomagnetic activity. Conditions applied were the category level of activity on the initial and subsequent day and the portion of the solar sunspot cycle. Conditional probabilities were determined for 100 successive days after the initial day, both for the quiet and active portions of the sunspot cycle. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: In Nordic literature a remarkable discussion of the northern light appears in Kongespeilet (The King's Mirror) a thirteenth-century Norwegian chronicle. It is described in vivid detail as the following translated excerpts demonstrate: These northern lights have this peculiar nature, that the darker the night is, the brighter they seem, and they always appear at night but never by day, most frequently in the densest darkness and rarely by moonlight. In appearance they resemble a vast flame of fire viewed from a great distance. It also looks as if sharp points were shot from this flame up into the sky; these are of uneven height and in constant motion, now one, now another darting highest; and the light appears to blaze like a living flame. Three different theories for the origin of the northern light were suggested in this book. Numerous naturally occurring heavenly phenomena have been observed and enjoyed as long as the Earth has been inhabited, but hardly any of them has stirred man's imagination, curiosity and fear as much as the northern light. The northern light is certainly one of the most spectacular of nature's phenomena.

This book was released on 2020-08-18 with total page 56 pages. Available in PDF, EPUB and Kindle. Book excerpt: Previous studies have shown geomagnetic indices to be useful for providing early estimates for the size of the following sunspot cycle several years in advance. Examined this study are various precursor methods for predicting the minimum and maximum amplitude of the following sunspot cycle, these precursors based on the aa and Ap geomagnetic indices and the number of disturbed days (NDD), days when the daily Ap index equaled or exceeded 25. Also examined is the yearly peak of the daily Ap index (Apmax), the number of days when Ap greater than or equal to 100, cyclic averages of sunspot number R, aa, Ap, NDD, and the number of sudden storm commencements (NSSC), as well the cyclic sums of NDD and NSSC. The analysis yields 90-percent prediction intervals for both the minimum and maximum amplitudes for cycle 24, the next sunspot cycle. In terms of yearly averages, the best regressions give Rmin = 9.8+/-2.9 and Rmax = 153.8+/-24.7, equivalent to Rm = 8.8+/-2.8 and RM = 159+/-5.5, based on the 12-mo moving average (or smoothed monthly mean sunspot number). Hence, cycle 24 is expected to be above average in size, similar to cycles 21 and 22, producing more than 300 sudden storm commencements and more than 560 disturbed days, of which about 25 will be Ap greater than or equal to 100. On the basis of annual averages, the sunspot minimum year for cycle 24 will be either 2006 or 2007. Wilson, Robert M. and Hathaway, David H.

Available in PDF, EPUB and Kindle. Book excerpt: This volume is dedicated to the Solar Dynamics Observatory (SDO), which was launched 11 February 2010. The articles focus on the spacecraft and its instruments: the Atmospheric Imaging Assembly (AIA), the Extreme Ultraviolet Variability Experiment (EVE), and the Helioseismic and Magnetic Imager (HMI). Articles within also describe calibration results and data processing pipelines that are critical to understanding the data and products, concluding with a description of the successful Education and Public Outreach activities. This book is geared towards anyone interested in using the unprecedented data from SDO, whether for fundamental heliophysics research, space weather modeling and forecasting, or educational purposes.

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.
