A powerful G4 (Severe) geomagnetic storm is headed our way, and there’s a buzz about the possibility of witnessing the northern lights at more southern locations, including here in Columbus.
Here’s everything you need to know about the storm and your chances of catching this rare sight.
What’s causing this storm?
The storm is the result of a coronal mass ejection (CME) launched from the Sun’s active region 3848. This CME, which carries billions of tons of charged particles, is heading directly toward Earth. When it hits, it will cause disturbances in Earth’s magnetic field, creating conditions that may trigger stunning auroras.
When will the CME hit?
Forecasts from NOAA confirmed that the CME impacted Earth today around 11:15 a.m. EST. The effects could last for up to 24 hours. The best time for aurora viewing in Columbus would be after sunset, as long as the storm continues into the evening.
So, what exactly are the Northern Lights, and why are they suddenly appearing in Ohio?
Known scientifically as the aurora borealis, these lights are the result of solar particles colliding with Earth’s magnetic field. This interaction causes vivid displays of dancing lights, primarily seen near the poles. However, an active solar cycle increases the frequency and intensity of these solar storms, pushing the auroras to lower latitudes.
Tonight’s Aurora chances
The green line on the map above shows the farthest south that we might be able to see the Northern Lights on Thursday evening on the horizon. The area shaded in green will be able to see the Northern Lights overhead! Columbus will be in prime viewing rang for the aurora this evening. The best way you can check before heading out to hunt for the aurora tonight is to check the 30 minute space forecast available at NOAA.gov.
For those in Ohio dreaming of witnessing this event, here’s a simple guide to maximizing your chances of catching the Northern Lights in all their glory:
1. Timing is Everything
The best time to spot auroras is between 11 p.m. and 2 a.m. This window provides the darkest skies, which is essential for spotting the faint glow of the auroras on the horizon. That said, depending on the intensity, you could see the aurora as early as just a few hours after sunset.
2. Escape the City Glow
Light pollution is a major barrier to aurora viewing. Find a spot far from city lights where the sky is dark. State parks or rural areas are often good bets. The darker the environment, the better your chances of seeing the Northern Lights.
3. Aim High
Elevation can be your friend when trying to spot auroras. A higher vantage point might give you a clear line of sight over obstacles and light pollution. However, don’t fret if you can’t get up high; a clear, dark sky is more important.
4. Weather Watch
Cloud cover is the enemy of aurora viewing. Before planning your night under the stars, check the weather forecast. Clear skies are crucial for a successful aurora hunt. The skies are looking fairly clear for viewing this evening.
5. Horizon Gazing
Unlike those closer to the Arctic Circle, where the auroras often arc overhead, Ohioans should focus on the horizon. The lights might appear as subtle, moving glows. Patience is key, as the display can vary in intensity and duration.
What’s next?
It’s important to remember that aurora viewing in Ohio is still a rare and unpredictable event, but space weather forecasters are optimistic. Keep an eye on space weather reports throughout the day and be sure to check the 30-minute forecaster from NOAA Space Weather Prediction Center for your best chance to see the aurora.
