This book is devoted to eruptive phenomena on the Sun, the most dangerous sources of space weather disturbances. It discusses the latest achievements in this field, described in the scientific literature and obtained by the author himself. The initial chapters of the book give a brief description of the role of the Sun in the life and history of mankind, a general description of the solar interior and the atmosphere of the Sun, the causes and drivers of solar activity and its impact on the Earth's environment and human life. The book provides a detailed description of eruptive phenomena on the Sun, a review of observations of solar activity and theoretical ideas about the mechanisms and causes of a sudden release of energy in the solar atmosphere. Much attention is paid to the solar magnetic fields, their characteristic features and measured values in the photosphere, the observed manifestations in the chromosphere and corona, and methods for extrapolating photospheric data to the upper layers of the solar atmosphere. It is assumed that the magnetic field is the source of energy suddenly released during eruptive phenomena observed in the form of flares, prominence eruptions and coronal mass ejections (CMEs). Energy is accumulated and stored in the non-potential (associated with electric currents) part of the coronal magnetic field (free magnetic energy). This part of the field is the most variable and can provide energy for fast eruptive processes. CMEs, propagating through the interplanetary medium, significantly perturb it and cause the strongest geomagnetic storms when they affect the Earth's magnetosphere. The prediction of the arrival of the CME is the key problem of the entire space weather forecast. Thus, pre-eruptive conditions in CME source regions are of great importance. Solar prominences and filaments are considered the most likely progenitors of CMEs. Most of the book is devoted to the description and analysis of their equilibrium and stability. It is shown that there are measurable characteristics of the proximity of the prominence to the instability threshold, which can be very useful in the problem of space weather forecasting. The book contains many illustrations and links to the latest scientific articles and reviews on the topic. It will be useful to researchers in the field of astrophysics, solar physics, geophysics, as well as PhD and graduate students.

A major goal of our MURI project was to develop a state-of-the-art, observationally- tested 3-d numerical modeling system for predicting magnetic eruptions on the Sun and their interplanetary consequences. This project is motivated by the fact that the Sun drives the most violent space weather events. The mechanisms that trigger and drive these eruptions are the least understood aspects of space weather. A better physical understanding of how magnetic eruptions occur and how these disturbances propagate will surely lead to more accurate and longer range forecasts.

Forecasting the time, place, and character of a volcanic eruption is one of the major goals of volcanology. It is also one of the most difficult goals to achieve. Until recently, people living in a volcano's shadow had little help anticipating an eruption. A major volcanic event might strike with no warning at all. In the past 300 years, volcanic eruptions, most of them unexpected, have killed more than 250,000 people. In 2000, experts estimated that 500 million people were living in areas at risk from catastrophic volcanic eruptions. This book describes the strides that have made in eruption forecasting in recent years and explores why accurately predicting volcanic events remains difficult. Based on the methodologies in this book, Eruption Pro 10.6, to our knowledge, it is the only software programme of its type anywhere in the world. Eruption Pro 10.6 performs analysis on current available volcano eruption data from both historical and current available eruption data, near real-time measurement data including, seismic, deformation, thermal, frequency of eruption analysis, solar & lunar influences, crater lake temperature (if applicable), COSPEC, & statistical procedures. The newest version also accounts for, albeit very small, contributions due to lunar and solar influences.

Published by the American Geophysical Union as part of the Geophysical Monograph Series, Volume 165. Coronal mass ejections (CMEs) are the most energetic events in the heliosphere. During solar cycle 23, the close connection between CMEs and solar energetic particles (SEPs) was studied in much greater detail than was previously possible, including effects on space weather. This book reviews extensive observations of solar eruptions and SEPs from orbiting and ground-based systems. From SOHO and ACE to RHESSI and TRACE, we now have measurements of unprecedented sensitivity by which to test assumptions and refine models. Discussion and analysis of: Coronal mass ejections and energetic particles over one solar cycle Implications of solar eruptions for space weather and human space exploration The elemental, isotopic, and ionic charge state composition of accelerated particles Complex interconnections among CMEs, flares, shocks, and energetic particles will make this book an indispensable resource for scientists working on the Sun-Earth connection, including space physicists, magnetospheric physicists, atmospheric physicists, astrophysicists, and aeronomists.

The First Edition of The Sun from Space, completed in 1999, focused on the early accomplishments of three solar spacecraft, SOHO, Ulysses, and Yohkoh, primarily during a minimum in the Sun’s 11-year cycle of magnetic activity. The comp- hensive Second Edition includes the main ndings of these three spacecraft over an entire activity cycle, including two minima and a maximum, and discusses the signi cant results of six more solar missions. Four of these, the Hinode, RHESSI, STEREO, and TRACE missions were launched after the First Edition was either nished or nearly so, and the other two, the ACE and Wind spacecraft, extend our investigations from the Sun to its varying input to the Earth. The Second Edition does not contain simple updates or cosmetic patch ups to the material in the First Edition. It instead contains the relevant discoveries of the past decade, integrated into chapters completely rewritten for the purpose. This provides a fresh perspective to the major topics of solar enquiry, written in an enjoyable, easily understood text accessible to all readers, from the interested layperson to the student or professional.

Major flare eruptions in solar active regions create geophysical disturbances which may seriously disrupt Air Force communication and surveillance systems. This report discusses interferometric observations of solar active regions which show that small-scale, highly circularly polarized sources dominate solar emission at radio wavelengths. The small-scale sources emit intense circularly polarized radiation immediately prior to and during the eruption of solar flares, whereas the circularly polarized emission remains at a lower, constant level whenever the active regions are quiescent and not erupting. The circular polarization of the flare precursors indicates a direct connection with changing magnetic fields in the solar active regions. The precursors reflect changing magnetic fields which may trigger subsequent flare eruptions, and these trigger sources may serve as reliable flare predictors. Studies of the changes in circularly polarized emission during the flare eruptions suggest that the flare eruption process is also the result of changes in magnetic fields. This report further discusses the synthesis mapping technique in which simultaneous solar observations with as many as 55 different interferometer pairs have been used to produce radio wavelength maps of active regions with second of arc angular resolution.
