A somewhat personalized overview is presented of the effects of solar-terrestrial processes on electrical technologies, beginning with the electrical telegraphs in the mid-eighteenth century to the current era of extensive ground- and space-based commercial and governmental technical systems including national security upon which modern society depends. As human technologies increased in diversity over the last century and a half, space weather effects have continued to be of significant importance in the successful design and operations of many of these technologies. Within a few decades in the early to mid 19th century, the electrical telegraph had revolutionized communications within countries, and across countries and oceans Standage The telegraph had eliminated the line of sight semaphore signaling that had begun to be emplaced across Europe in the late 18th century Napoleon had planned a line to Boulogne in preparation for his invasion of England , and in the eastern U. Such signaling required significant manpower for relaying, and could often be obscured by weather.

On May 23, , amidst the high-strung economic and political tension of the Cold War, all three of the United States' ballistic missile early-warning radars became simultaneously jammed. Located in the high-latitude areas of Alaska, Greenland, and the United Kingdom, these radars were designed to detect incoming Soviet missiles, and any attack or disruption of these radars were considered to be an act of war. The United States Air Force, believing their radars had been intentionally jammed by the Soviet Union, authorized aircraft with nuclear-strike capabilities to take to the skies.

Solar storms of different types are caused by disturbances on the Sun, most often coronal clouds associated with coronal mass ejections CMEs produced by solar flares emanating from active sunspot regions, or, less often, from coronal holes. Solar filaments solar prominences may also trigger CMEs, trigger flares, or occur in conjunction with flares, and the associated CMEs can be intensified. Active stars produce disturbances in space weather with the field of heliophysics , the science that studies such phenomena; itself primarily an interdisciplinary combination of solar physics and planetary science long-term space weather patterns comprise space climate. In the Solar System , the Sun can produce intense geomagnetic and energetic particle storms capable of causing severe damage to technology including but not limited to large scale power outages , disruption or blackouts of radio communications including GPS , and temporary to permanent disabling of satellites and other spaceborne technology. Intense solar storms may also be hazardous to high-latitude, high-altitude aviation  and to human spaceflight.

The storm made its initial mark at Earth with a colossal solar radio burst causing radio interference at frequencies between 0. Substantial fast EUV-associated and slow soft Xray-associated magnetic crochets were observed. Within hours a solar energetic particle event disrupted high-frequency communication in the polar cap. Subsequently, record-setting geomagnetic and ionospheric storms compounded the disruptions.

- Повисла продолжительная пауза. - Прости, что я тебе лгал. Попытка переделать Цифровую крепость - дело серьезное и хлопотное. Я не хотел тебя впутывать. - Я… понимаю, - тихо сказала она, все еще находясь под впечатлением его блистательного замысла. - Вы довольно искусный лжец. Стратмор засмеялся.
Мидж… Она прекратила печатать и повернулась к. - Чед, список будет распечатан в течение тридцати секунд. Вот мои условия. Ты даешь мне ключ. Если Стратмор обошел фильтры, я вызываю службу безопасности. Если я ошиблась, то немедленно ухожу, а ты можешь хоть с головы до ног обмазать вареньем свою Кармен Хуэрту. - Мидж зло посмотрела на него и протянула руку.
- Мы опустим каждый второй кадр вместе со звуковым сопровождением и постараемся держаться как можно ближе к реальному времени. На подиуме все замолчали, не отрывая глаз от экрана.
