A Celestial Spectacle Unfolds: Witnessing and Capturing the Aurora Borealis This Weekend
A powerful geomagnetic storm is surging across Earth, and the resulting impact could paint the night skies of the United States with a breathtaking display of the aurora borealis, also known as the Northern Lights. This weekend might be your chance to witness this mesmerizing natural phenomenon, even if you live far north of the Arctic Circle. Let’s delve into the science behind this celestial ballet, explore ways to maximize your chances of seeing it, and discover how to capture the aurora’s magic using your smartphone!
The Allure of the Aurora Borealis
The aurora borealis is a luminous light display that dances across the night sky in vibrant greens, reds, purples, and yellows. This captivating phenomenon occurs when charged particles from the sun, called solar wind, collide with gases in Earth’s upper atmosphere. The specific gas molecules struck determine the color of the aurora: oxygen ignites in vibrant greens, while nitrogen shimmers in shades of purple and red.
A Geomagnetic Glimpse for Millions
Sophisticated auroral prediction models are abuzz with excitement, and maps generated by the National Oceanic and Atmospheric Administration (NOAA) paint a promising picture. A band of green and red lights might be visible across the northern half of the US, potentially stretching as far south as Alabama and Northern California. This is a significant southward reach for the aurora borealis, typically only gracing higher latitudes.

Chasing the Lights: How to Increase Your Odds
While the geomagnetic storm presents a heightened possibility of auroral displays, it’s important to manage expectations. Weather conditions significantly impact visibility. Here are some tips to maximize your chances of witnessing this celestial spectacle:
Head North: The farther north you travel, the stronger the aurora is likely to be.
Escape Light Pollution: Seek out a location with minimal light pollution for the best view. Cities tend to wash out the faint auroras.
Embrace the Night: Auroras are most visible during the wee hours, typically between 10 pm and 3 am.
Dress for the Occasion: Nighttime temperatures can drop significantly, especially at higher latitudes.
Check the Forecast: Stay updated on the latest auroral predictions and weather conditions.
Bring a Camera: With the right settings, you can capture stunning photographs of the aurora.
The Aurora Borealis Observatory in Norway offers a luxurious experience for aurora borealis enthusiasts. While capturing the phenomenon on film requires specialized equipment, the observatory’s pristine location and expert guides ensure optimal viewing conditions for an unforgettable night under the dancing lights.
Capturing the Moment: Smartphone vs. Fancy Camera
While a camera with manual settings offers the best results for capturing the aurora borealis in all its glory, you can still create decent real-time footage using your smartphone. Here’s a breakdown of two approaches:
Smartphone Photography:
Hello Aurora recommends switching to Photo mode for longer exposure times compared to Video mode. This allows for more light to be captured, resulting in a clearer image.
Once you’ve framed the aurora, lock the focus and exposure to ensure consistent settings throughout your recording.
Use your phone’s screen recording feature to capture the real-time movement of the aurora. You can edit the footage later to remove unnecessary parts and adjust brightness and contrast for a more vivid look.
Consider downloading a third-party app like NightCap to improve low-light visibility on your phone’s camera.
DSLR or Mirrorless Camera:
Visit Iceland suggests using Night mode on iPhone 11 Pro or newer models to adjust exposure time (around 10-15 seconds). Experiment with different settings to find the optimal balance for capturing the aurora’s movement and detail.
Use a tripod for stability and manual controls to adjust ISO, shutter speed, and aperture for the best low-light performance.
A Once-in-a-Lifetime Opportunity
This weekend’s geomagnetic storm presents a unique opportunity for millions of Americans to witness the captivating beauty of the aurora borealis. So, dust off your winter gear, find a dark location, and prepare to be awestruck by nature’s light show!
