Solar activity causes changes in the magnetic field on the surface of the Earth. If these changes are insignificant, they do not affect life on Earth. However, rapid variations of the geomagnetic field, the so-called magnetic storms, which have the character of shock waves, may adversely affect living organisms (including humans), and the technical systems that people use. The book presents a conceptual design that allows prediction of electrical power system emergency conditions caused by magnetic storms. Finally, the authors' present a comprehensive analysis of perturbations in the low- and mid-latitude ionosphere during moderate recurrent geomagnetic storms.

The verage morphology of magnetic storms with sudden commencement was studied with 346 magn tic storms that occurred in the years 1902 to 1945. Magnetic recor from 26 observatories were used. The 346 storms were classed into three intensity groups of great, moderate and weak storms, and their morphology was investig ted s par t ly S OR VARI TION WAS ANALYZED INTO WO PARTS, Dst and DS. DS was naly ed harmonically, and its changes with storm time were studied in great detail. The author's present views on stor sudden commencements and on the b ormal nature of t e storm variations at the geomagnetic equator are briefly reviewed. (Author).

"[Man's] life consists in a relation with all things: stone, earth, trees, flowers, water, insects, fishes, birds, creatures, sun, rainbow, children, women, other men. But his greatest and final relation is with the sun..".by David Herbert. In addition to sustaining life on our planet Earth, the Sun is a source of various phenomena that controls both terrestrial and space weather. This book introduces the reader to the basic science governing the Solar-Terrestrial interactions. It outlines some fundamental principals of solar activity and related solar storms which, by interaction with the earth's magnetosphere can often lead to the disruption of the human modern infrastructures. This is known as space weather and various aspects of it are briefly described in this document. In addition to the theoretical description of the solar-terrestrial phenomena, their systematic monitoring and analysis is done with focus on solar activity cycle twenty three period. As one of the primary goals in space physics study is to develop models to predict space weather, this aspect has also been described in this book.

We report two ground-level observations, of geomagnetic storms of different origins; they are among the highest geomagnetic storms, in the solar Cycle 24. The first is St. Patrick's Day storm on March 17, 2015, originated by the impact on Earth's atmosphere of coronal mass ejections (CMEs), the storm reaching the condition of G4 (severe) level, in the NOAA geomagnetic scale. The second included the major geomagnetic storm whose origin is attributed to the interaction with the Earth of a High-Speed Stream (HSS) ahead of a positive polarity coronal hole on October 7, 2015. This storm reached the condition G3 (strong) level. We give emphasis to observations detected by the New-Tupi muon telescopes, located at sea level in Brazil (22.53° S, 43.13° W). We present a study of these observations in correlation with observations reported by multipoint space-based measurements, such as the ACE at Lagrange Point L1 and the geostationary GOES weather satellite, including two global geomagnetic indices and several ground-based detectors. Some considerations on the influence of these geomagnetic storms in the Earth weather are reported.

Investigation of data on strong and very strong magnetic storms of at least two days duration, recorded by the Murmansk Division of the Institute of Terrestrial Magnestism, Ionosphere, and Radio Wave Propagation of the Academy of Sciences of the USSR during the period 1 January 1955 to 31 July 1959, has shown that there is a tendency of magnetic storms to recur at approximately equal periods of time. The most frequently observed periods were: 14 plus or minus 1, 26 plus or minus 1, 29 plus or minus 1 and 56 plus or minus 1 days. Cyclogenesis developed more actively from the second day after the commencement of the magnetic storm to the second day after its termination, and the development of low cyclones into high-lvevel cyclones was accelerated. At the time of magnetic storms during the cold season, there is a tendency for cyclonic activity to intensify from Iceland toward the Barents Sea. In the warm season, during magnetic storms, there is a tendency for the temperature to rise in this same region. The article includes an analysis of processes during two magnetic storms. (Author).

The average morphology is described of geomagnetic storms with sudden commencement. A numerical intensity index was assigned to each of 346 storms occurring in 1902--45. On the basis of these indices the storms were divided into three sets, of 136 weak, 136 moderate, and 74 great storms. Their morphology was studied separately. For weak storms records were analyzed from 26 magnetic observatories, ranging in geomagnetic latitude from 80 deg N to 48 deg S; and for moderate and great storms, from 19 observatories, 80 deg N to 1 deg S. The stormtime variation Dst and the disturbance longitudinal inequality DS were determined for the first three storm days for different latitudes. The DS variation was obtained, and harmonically analyzed, for each of the first 8 quarter-day intervals and for the succeeding three 8-hour intervals. New features of storm morphology during the first few hours of storm time were discovered: namely, that DS reaches its maximum in about two or three hours from the storm commencement, and that its phase rapidly changes during the first few storm hours.

Geomagnetic storms - a type of space weather that creates disturbances that affect the planet's magnetic field - have the potential to cause significant damage across the globe with a single event. Severe geomagnetic storms can disrupt the operation of electric power transmission systems and critical infrastructures relying on space-based assets. A geomagnetic storm that degrades the electric power grid would affect not only the energy sector but the transportation, communications, banking, and finance sectors, as well as government services and emergency response capabilities. Despite the potentially serious consequences of a severe geomagnetic storm, a literature review indicates that the state of the art for assessing the security risk from geomagnetic storms is still in development. There are examples of analyses that describe threat, vulnerability, and consequence, but they are not integrated, primarily because of the weakness in the threat analysis. Without a sense of the likelihood of such events or at least a mechanism for relative comparisons, cost-benefit analyses have been unable to demonstrate the utility of investing either in hardening or in testing and maintaining operational procedures. The Federal government lacks comprehensive national-level geomagnetic storm risk management assessments and strategies, and no standing entity exists to coordinate cross-Federal government geomagnetic storm risk analysis. This Issue Brief suggests that the Federal government should consider whether it is appropriate to conduct a formal, comprehensive risk assessment regarding severe geomagnetic storms.
