Prepare for a Spectacular Show: The Northern Lights May Dazzle Across a Dozen States!
This week, a surge in solar activity is set to illuminate the night skies with the breathtaking northern lights, potentially visible in over a dozen states.
According to a recent alert from the National Oceanic and Atmospheric Administration's (NOAA) Space Weather Prediction Center, significant expulsions of plasma and magnetic fields from the sun—known as coronal mass ejections—are anticipated to reach Earth around midday on December 9. This event is likely to trigger heightened geomagnetic activity, making the auroras more vibrant and widespread.
On the K-index scale, which measures how far from the poles the northern lights can be seen, NOAA forecasts a score of 5 out of 9 for December 9. A Kp score in the range of 3 to 5 typically indicates a more brilliant display of the auroras.
In terms of geomagnetic storm classification, NOAA has rated this event as a G1, categorizing it as a minor storm.
The northern lights, scientifically referred to as the aurora borealis, create stunning displays of color in the night sky due to the interaction between solar plasma and Earth's magnetic field, as explained by the National Weather Service.
When Can You See the Northern Lights?
The auroras are not visible during the day and are best observed shortly after sunset or just before sunrise. For optimal viewing, the ideal time is usually within an hour or two of midnight, according to NOAA.
Where Will the Northern Lights Be Visible?
NOAA's forecast indicates that parts of approximately 15 states fall within the predicted "view line" for the northern lights on December 9. This view line marks the southernmost point from which the auroras might be visible on the northern horizon.
However, it's important to note that this forecast is merely a prediction. As NOAA states, "The aurora does not need to be directly overhead but can be observed from as far as 1,000 km away when conditions are favorable and the aurora is particularly bright."
For instance, during a strong geomagnetic event on November 11, observers reported sightings of the auroras in southern states like Texas, Florida, and Colorado, all of which were beyond the expected view line for that night.
The following states are likely to witness the aurora, based on NOAA's forecasted view line:
- Alaska
- Idaho
- Iowa
- Maine
- Michigan
- Minnesota
- Montana
- New Hampshire
- New York
- North Dakota
- South Dakota
- Vermont
- Wyoming
- Washington
- Wisconsin
