The incredible light show hit several states of the United States of America, and quite naturally, people couldn’t keep calm!
From capturing breathtaking images of the wondrous phenomenon of Mother Nature to sharing stunning clippings on social media – thanks to the enthusiastic bunch of netizens – the internet has been painted in pretty colors!
Take a look:
What happened?
Over the weekend, a powerful geomagnetic storm , rated G4 (severe) by NOAA, illuminated the night skies across much of the United States, offering a rare and breathtaking display of the Aurora Borealis , or Northern Lights . This event was triggered by a significant coronal mass ejection (CME) from the sun, sending a surge of charged solar particles toward Earth. The interaction of these particles with Earth's magnetic field caused the vibrant light show visible even in regions far south of the typical auroral zone.
What Is the Aurora Borealis?
The Aurora Borealis occurs when charged particles from the sun interact with Earth's magnetic field and atmosphere. These particles collide with gases like oxygen and nitrogen, causing them to emit light. The resulting displays can range from faint glows to vivid, multicolored curtains of light. The colors observed depend on the type of gas and the altitude at which the collisions occur.
The Aurora Borealis, or Northern Lights, is one of Earth's most mesmerizing natural phenomena. This ethereal light display, primarily visible in high-latitude regions near the Arctic and Antarctic, captivates observers with its vibrant colors and dynamic patterns.
It’s not only the locals who go gaga over the light show; photographers and travelers alike seek out these celestial spectacles, capturing images that showcase the awe-inspiring beauty of our planet's atmosphere.
The Science behind the magic:
When solar winds, composed of charged particles from the sun, reach Earth, they can disturb Earth's magnetic field. This disturbance funnels the particles toward the magnetic poles, where they collide with atoms and molecules in Earth's atmosphere. These collisions excite the atoms, causing them to light up and produce the colorful displays we observe as auroras.
Best places to witness the Aurora:
To experience the Northern Lights firsthand, consider visiting locations within the auroral zone:
Tromsø, Norway: Located above the Arctic Circle, Tromsø offers prime viewing opportunities during the winter months. The city's clear skies and minimal light pollution make it an ideal destination for aurora enthusiasts.
Abisko, Sweden: Known for its "blue hole" in the sky, Abisko provides consistent clear skies, enhancing the chances of witnessing the aurora. The Abisko National Park is a popular spot for aurora viewing.
Fairbanks, Alaska, USA: Situated under the auroral oval, Fairbanks experiences frequent auroral activity. The city's location and cold, clear nights make it a prime location for aurora viewing.
Yellowknife, Canada: Located in the Northwest Territories, Yellowknife boasts clear skies and minimal light pollution, offering excellent conditions for observing the Northern Lights.
Aurora viewing tips:
If you're planning to see the Northern Lights, it's essential to check solar activity forecasts and weather conditions to maximize your chances.
Choose the right time: The best time to view the aurora is during the winter months, from late September to early April, when nights are longest.
Find dark locations: Seek out areas away from city lights to reduce light pollution.
Check solar activity: Monitor solar activity forecasts, as increased solar activity can enhance auroral displays.
Be patient: Auroras can appear suddenly and may last for varying durations. Patience and persistence are key.
