What is Space Weather and What are the Impacts?
We rely on advanced technology for almost everything we do. Satellite communications, GPS applications, and the electric power grid provide the backbone of our Nation’s economic vitality and national security. These technologies are vulnerable to a threat from space – our Sun! To learn about space weather visit www.swpc.noaa.gov/about-space-weather
Satellites, GPS, the power grid, and more can be vulnerable to a space threat - our Sun! Learn morewww.swpc.noaa.gov/about-space-weather #SpaceWeather
Space Weather Impacts on Communications
Effective communication systems are critical. Aviation and emergency response communities depend on reliable communications. Radio and satellite communication technologies can experience significant degradation from space weather storms.

Space Weather Impacts on the Power Grid
The electric power grid, and consequently the power to your home or business, can be disrupted by space weather. Extreme geomagnetic storms can create significant impacts, damaging critical assets and even causing blackouts in rare cases.

Space Weather and the Aurora Borealis
The Aurora Borealis (Northern Lights) are the result of electrons colliding with Earth’s upper atmosphere. When space weather activity increases, the aurora may be visible. During large events, the aurora may be observed as far south as the U.S., Europe, and Asia. Keep in mind, to observe the aurora, the skies must be dark, clear, and free of clouds. To learn about the aurora http://www.swpc.noaa.gov/phenomena/aurora #SpaceWeather
The aurora may be seen over the U.S. during major solar storms. http://www.swpc.noaa.gov/phenomena/aurora
The OVATION Aurora Forecast Model shows the intensity and location of the aurora predicted for the time shown at the top of the map. This probability forecast is based on current solar wind conditions.
Note: A 3-day aurora forecast is now available as a test product!
What are Solar Flares?
Solar flares are huge explosions of electromagnetic radiation from the Sun lasting from minutes to hours. They are seen as a bright area on the sun in optical wavelengths and as bursts of noise in radio wavelengths. Solar flares occur in a large range of strengths, have emissions that travel at the speed of light, and reach Earth in eight minutes. They can cause radio blackouts on the sunlit side of the Earth.

What are Coronal Mass Ejections?
Coronal Mass Ejections (CMEs), are explosive eruptions of plasma from the Sun’s outer atmosphere, the Corona. A CME typically carries roughly a billion tons of material outward from the Sun at millions of miles per hour (thousands of km/s). CMEs are not particularly bright and may take hours to fully erupt from the Sun and typically take 1-4 days to travel to Earth. To learn about CMEs visit http://www.swpc.noaa.gov/phenomena/coronal-mass-ejections #SpaceWeather Photo from NASA
Clouds of plasma that erupt from the sun are called Coronal Mass Ejections. Learn more www.swpc.noaa.gov/phenomena/coronal-mass-ejections #spaceweather photo @NASA

Emergency Communications Plan
An extreme space weather event could cause problems with mobile phones. Your family may not be together when this happens so it is important to plan in advance: how you will contact one another; how you will get back together; and what will you do in different situations. Create a Family Communications Plan. http://www.ready.gov/make-a-plan #SpaceWeather
If space weather interrupts cell phone usage, how will you contact your family? http://www.ready.gov/make-a-plan #SpaceWeather
