Understanding the Recent Pink Auroras: A Colorful Phenomenon

Chapter 1: The Intrigue of Pink Auroras
Recently, the sky over Tromsø, Norway, showcased an unexpected spectacle—pink auroras. Typically, auroras display hues of green, red, maroon, or purple. However, the vibrant pink tones observed in early November 2022 took many by surprise, including those who frequently chase these natural wonders.

Section 1.1: The Source of the Spectacle
Pink auroras are produced through a fascinating interplay of atmospheric and solar phenomena. The captivating light show emerges when intense solar winds are released from the Sun and penetrate the Earth's magnetic field, creating openings in the magnetosphere. As a result, high-energy charged particles enter these gaps, leading to geomagnetic storms.
Subsection 1.1.1: A Unique Observation
Captured by Markus Varik, a tour guide focused on aurora sightings, the rare pink display was highlighted on the Greenlander Facebook page. Varik noted, "The aurora borealis didn’t even resemble what we typically see. It was the strongest pink/purple I’ve ever witnessed, occurring unexpectedly early in the evening. We were fortunate to experience it."
Section 1.2: The Science Behind the Colors
Most commonly, auroras appear in shades of green, red, maroon, or purple. The extraordinary pink observed by Varik is attributed to nitrogen particles found in the lower atmosphere, around 100 kilometers above the surface—an area typically untouched by solar winds. The presence of charged particles in this region indicates an uptick in solar activity.
Chapter 2: The Impact of Geomagnetic Storms
The video titled "What Creates the Colors in the Northern Lights? - Causes of the Aurora Colors Explained" delves into the science of auroras and their colors, providing a deeper understanding of this phenomenon.
A G1-class geomagnetic storm recently impacted Earth, resulting in a significant opening in the magnetic field that lasted for approximately six hours. Prior to this event, NOAA’s Space Weather Prediction Center had issued alerts regarding the possibility of a G1 storm. Such storms can lead to minor disruptions in satellites and animal migrations, while also enhancing the visibility of these stunning light displays.
Interestingly, while these magnetic field openings may sound alarming, they pose little threat to life on Earth. Research shows that such holes can remain for many hours without adverse effects.
Looking ahead, solar activity is expected to peak around July 2025, yet current levels are already notably elevated. This increase bodes well for those wishing to witness the aurora borealis in the coming years.
Chapter 3: Best Locations for Aurora Viewing
The ideal time to seek out the aurora borealis spans from autumn through April. Although sightings cannot be guaranteed, certain locations are renowned for their higher chances of success. Reykjavik, the capital of Iceland, consistently ranks among the best spots, alongside Rovaniemi in Finland and Tromsø.
Moreover, auroras are not only visual phenomena; they can also produce sounds. Previously considered folklore, Finnish scientists confirmed in 2020 that these sounds do occur, potentially offering insights into their origins.
