The Hydro-Quebec electrical utility went from full operating capacity to blackout status in 92 seconds. Six million people were plunged into cold and darkness.  \nBelow is an example of a CME erupting from the Sun.  \nSource: NASA.  \nWHAT IS SPACE WEATHER?  \nActivity on the Sun can cause space weather storms that affect us here on Earth. Solar storms can impact the technology we rely on everyday: Global Positioning Systems (GPS), satellites, and electric power grids. Just as with other types of weather, the National Weather Service forecasts space weather disturbances and serves as the official source for civilian alerts and warnings.  \nSpace weather is a consequence of the behavior of the Sun, the nature of Earth’s magnetic field and atmosphere, and our location in the solar system. There are various phenomena that originate from the Sun that can result in space weather storms. Outbursts from huge explosions on the Sun—Solar Flares and Coronal Mass Ejections (CME)—send space weather storms hurling outward through our solar system. The Sun also emits a continuous stream of radiation in the form of charged particles that make up the plasma of the solar wind.  \nSolar Particle Events  \nrelease large numbers of high energy charged particles, predominately protons and electrons, which are accelerated to large fractions of the speed of light. These particles may arrive at Earth between 30 minutes and several hours.  \nSolar Flares  \nare huge explosionson the Sun. A flare appears as a sudden, intense brightening region on the Sun, typically lasting several minutes to hours. Flares are seen as bright areas on the Sun in optical wavelengths and as bursts of noise in radio wavelengths. The primary energy source of flares is the tearing and reconnection of strong magnetic fields. The electromagnetic emission produced during flares travels at the speed of light, taking about  \n8 minutes—rapidly affecting the dayside of Earth.  \nCoronal Mass Ejections  \nare explosive outbursts of plasma from the Sun’s outer atmosphere, the Corona. The blast of a CME typically carries roughly a billion tons of material outward from the Sun at speeds as fast as hundreds of kilometers per second. A CME contains particle radiation (mostly protons and electrons) and powerful magnetic fields. In contrast to solar flares, CMEs are not particularly bright, may take hours to fully erupt from the Sun, and typically take 1-4 days to travel to Earth.  \nSPACE WEATHER | 2  \nSPACE WEATHER AND THE SOLAR CYCLE  \nThe number of sunspots on the surface of the Sun increases and decreases in solar cycles of approximately 11 years. Solar Minimum refers to the several years when the number of sunspots is lowest; Solar Maximum occurs in the years when sunspots are most numerous. The Sun is usually very active when sunspot counts are high, however, severe storms can occur anytime during the solar cycle. Sunspots show where the Sun’s magnetic field energy is building up and where it could release to cause solar flares and CMEs. The Sun gives off more radiation than usual during solar maximum. This extra energy creates changes in the Earth’s upper atmosphere.  \nSunspots  \nare dark, cooler areas on the solar surface that contain strong, constantly shifting magnetic fields. A moderate-sized sunspot is many times larger than the size of the Earth.  \nSunspots form over periods lasting from days to weeks, and can persist for weeks and even months before erupting or dissipating.  \nSunspots occur when strong magnetic fields emerge through the solar surface and allow the area to cool slightly, from a background value of 6000°C down to about 4200°C. This cooler area appears as a dark spot on the S","cbCaiu2DqBwqzRh2","https://ap.wps.com/l/cbCaiu2DqBwqzRh2","pdf",4321402,12,"English","# Space Weather\n## Storms from the Sun\n## What is Space Weather?\n## Solar Particle Events\n## Solar Flares\n## Coronal Mass Ejections\n## Space Weather and the Solar Cycle\n## What Are the Impacts of Space Weather?","[{\"question\":\"What is space weather and what causes it?\",\"answer\":\"Space weather is caused by behavior of the Sun, Earth’s magnetic field and atmosphere, and Earth’s location in the solar system.
