The aurora borealis is usually green in color, although it can also appear to be a range of other colors, including red, blue, pink and purple. The color of the aurora is determined by the altitude in which it appears. Different atmosphere compounds (such as Nitrogen and Oxygen) are found at different altitudes. When charged particles from the Sun enter our atmosphere, they interact with those compounds, and the aurora is the visible result. Depending on which compounds are being excited by the Sun’s charged particles, different colors will result.

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. To learn about space weather impacts visit www.swpc.noaa.gov/impacts/hf-radio-communications and www.swpc.noaa.gov/impacts/satellite-communications #SpaceWeather

Although the Earth’s magnetosphere, ionosphere, and atmosphere do a great job protecting us from hazardous space weather, it is still possible for space weather to cause power outages. Find out more about #SpaceWeather impacts at swpc.noaa.gov/impacts/electric-power-transmission.

The sun is the main source of space weather, & it could even cause power outages! Find out more at swpc.noaa.gov/impacts/electric-power-transmission #SpaceWeather

The Aurora Borealis (Northern Lights) are the result of electrons colliding with the Earth’s upper atmosphere, and are visible when there is an increase in space weather activity. They can be observed in dark and clear areas of North America, Asia, and Europe. To learn more about auroras, visit swpc.noaa.gov/phenomena/aurora. #SpaceWeather

Solar flares are huge explosions of electromagnetic radiation from the Sun lasting from minutes to hours. They are seen as enhancements in optical and extreme ultraviolet/x-ray wavelengths; and can be detected 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. To learn about radio blackouts, visit www.swpc.noaa.gov/phenomena/solar-flares-radio-blackouts. #SpaceWeather

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 speeds that can reach millions of miles per hour (thousands of km/s). CMEs may take hours to fully erupt from the Sun and typically take one to four days to travel to Earth. When a CME arrives at Earth, it can lead to geomagnetic storming; especially when the embedded orientation of the magnetic field is opposite that of Earth's. To learn about CMEs visit http://www.swpc.noaa.gov/phenomena/coronal-mass-ejections. #SpaceWeather

Clouds of plasma that erupt from the Sun are called Coronal Mass Ejections. Learn more http://www.swpc.noaa.gov/phenomena/coronal-mass-ejections #SpaceWeather

Space weather is a two-sided coin: it creates beautiful auroras, but it can also jeopardize the technologies we rely on daily. See all the impacts of #SpaceWeather at weather.gov/space.
