Book excerpt: This study looked at observational and theoretical studies of flare physics, at quests for flare precursors, and at mathematical models for combining masses of predictive information. We also looked at the worldwide effort to gather and share timely data and combine it with knowledge and experience to forecast solar flares and their effects. Topics include: Long-lived, large-scale magnetic and velocity fields; Magnetic-energy buildup in an active region; Flare initiation; Flare precursors -- Filament activation, Preflare brightening, Magnetic shear, and Emerging and cancelling magnetic flux; Quantitative prediction; Operational solar flare prediction; Forecast evaluation.

Download or read book A Technique for Short Term Warning of Solar Energetic Particle Events Based on Flare Location Flare Size and Evidence of Particle Escape written by and published by . This book was released on 2009 with total page 20 pages. Available in PDF, EPUB and Kindle. Book excerpt: We have developed a technique to provide short-term warnings of solar energetic proton (SEP) events that meet or exceed the Space Weather Prediction Center threshold of J (>10 MeV) = 10 pr/sq cm/s/sr. The method is based on flare location, flare size, and evidence of particle acceleration/escape as parameterized by flare longitude, time-integrated soft X-ray intensity, and time-integrated intensity of type III radio emission at ~1 MHz, respectively. In this technique, warnings are issued 10 min after the maximum of> or = M2 soft X-ray flares. For the solar cycle 23 (1995-2005) data on which it was developed, the method has a probability of detection of 63% (47/75), a false alarm rate of 42% (34/81), and a median warning time of ~55 min for the 19 events successfully predicted by our technique for which SEP event onset times were provided by Posner (2007). These measures meet or exceed verification results for competing automated SEP warning techniques but, at the present stage of space weather forecasting, fall well short of those achieved with a human (aided by techniques such as ours) making the ultimate yes/no SEP event prediction. We give some suggestions as to how our method could be improved and provide our flare and SEP event database in the auxiliary material to facilitate quantitative comparisons with techniques developed in the future.
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.

Download or read book Extreme Events in Geospace written by Natalia Buzulukova and published by Elsevier. This book was released on 2017-12-01 with total page 800 pages. Available in PDF, EPUB and Kindle. Book excerpt: Extreme Events in Geospace: Origins, Predictability, and Consequences helps deepen the understanding, description, and forecasting of the complex and inter-related phenomena of extreme space weather events. Composed of chapters written by representatives from many different institutions and fields of space research, the book offers discussions ranging from definitions and historical knowledge to operational issues and methods of analysis. Given that extremes in ionizing radiation, ionospheric irregularities, and geomagnetically induced currents may have the potential to disrupt our technologies or pose danger to human health, it is increasingly important to synthesize the information available on not only those consequences but also the origins and predictability of such events. Extreme Events in Geospace: Origins, Predictability, and Consequences is a valuable source for providing the latest research for geophysicists and space weather scientists, as well as industries impacted by space weather events, including GNSS satellites and radio communication, power grids, aviation, and human spaceflight. The list of first/second authors includes M. Hapgood, N. Gopalswamy, K.D. Leka, G. Barnes, Yu. Yermolaev, P. Riley, S. Sharma, G. Lakhina, B. Tsurutani, C. Ngwira, A. Pulkkinen, J. Love, P.

Download or read book The Northern Light written by A. Brekke and published by Springer Science & Business Media. This book was released on 2012-12-06 with total page 181 pages. 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 1999-03-04 with total page 88 pages. Available in PDF, EPUB and Kindle. Book excerpt: In this study, the committee explores ways the National Weather Service (NWS) can take advantage of continuing advances in science and technology to meet the challenges of the future. The predictions are focused on the target year 2025. Because specific predictions about the state of science and technology or the NWS more than 25 years in the future will not be entirely accurate, the goal of this report is to identify and highlight trends that are most likely to influence change. The Panel on the Road Map for the Future National Weather Service developed an optimistic vision for 2025 based on advances in science and technology.
