Mostly, that energy is driven to the Earth’s North and South Poles, but the stronger the storm is, the more likely it is to be seen in lower latitudes like the southern United States. Green and red largely come from oxygen, and blue stems from nitrogen. The colors seen in the sky are dictated by where in the atmosphere the oxygen and nitrogen hit, Dr. That creates geomagnetic storms that produce the aurora. The energy comes from a coronal mass ejection, a large expulsion of plasma from the sun, which causes the magnetic field around Earth to shake. Alex Young, the associate director for science in the Heliophysics Science Division at NASA’s Goddard Space Flight Center. An aurora (PL: auroras or aurorae), also commonly known as the polar lights, is a natural light display in Earths sky, predominantly seen in high-latitude. If youre near the North Pole, it is called an aurora borealis or. The famed Northern Lights could be visible in parts of the UK again tonight as a solar flare from the Sun reaches our atmosphere. Aurora was the Roman goddess of dawn, and Boreas. Generally speaking, the Aurora Borealis will remain very active for two to three years either side of Solar Maximum which effectively means were heading into. Frequently there are beautiful light shows in the sky. The Space Weather Prediction Center at the National Oceanic and Atmospheric Administration rated the geomagnetic storm’s severity a Level 4 on its five-tier scale.Ĭatching a glimpse of the auroras requires electrons from solar wind to hit the electrons that are already trapped around earth’s magnetic field, which then acts like a slingshot, said C. In the early 17th century, the astronomer and scientist Galileo Galilei named this phenomenon Aurora Borealis. But on Thursday night, a “severe” geomagnetic storm brought the auroras to Minnesota, New York and Virginia, and the views even moved as far south as Arizona and North Carolina. The colorful streaks in the sky, also known as the northern lights, are often visible from places like Alaska, Canada and Iceland. We offer accommodations, as well as evening aurora tours for those who are. near Yellowknife, in Canadas Northwest Territories it is the best place in the world to see the Northern Lights, better known as Aurora Borealis.
