The Northern Lights, or aurora borealis, put on a show across much of the country earlier this week. But folks in Connecticut probably won’t catch them again on Thursday night.
Updated forecasts point to weaker solar storm activity. The dazzling display will pull back northward, so even with mostly clear skies, Connecticut’s chances look slim.

Why Connecticut Won’t See the Aurora Borealis Tonight
Earlier this week, three huge coronal mass ejections (CMEs) burst from the sun. Charged particles raced toward Earth’s magnetic field, sparking strong geomagnetic storms.
This surge pushed the aurora’s range much farther south than usual — even reaching parts of Connecticut. At the storm’s peak, it hit a G4, or “severe,” rating on NOAA’s five-level scale.
NOAA’s Space Weather Prediction Center now expects the intensity to drop to G3, which they call “strong.” That’s still impressive, but not enough for Connecticut skywatchers. The visible range for the aurora borealis will shift north, out of reach for the state.
From Stunning Views to Missed Opportunities
During the peak, people in Hartford, New Haven, and Danbury spotted faint, mesmerizing flashes overhead. Amateur photographers in Stamford and Norwalk scrambled to snap rare colors for local social media groups.
Even up in Torrington and Putnam, night sky fans caught glimpses usually reserved for folks living much farther north. But those hopes faded with the latest forecast, reported by Peter Yankowski of Hearst Connecticut Media Group on November 13, 2025.
Earlier predictions had oversold Thursday night’s chances. NOAA’s revised space weather models set the record straight.
Understanding the Science Behind Solar Storms
The aurora borealis happens when solar particles interact with our planet’s magnetic field. When CMEs erupt, they fling plasma into space. If those particles slam into Earth’s magnetosphere, a geomagnetic storm kicks off — just like the one earlier this week.
That’s what triggers those glowing curtains of light in the upper atmosphere. It’s wild to think about, really.
NOAA’s Geomagnetic Storm Scale
The NOAA scale runs from G1 (“minor”) to G5 (“extreme”):
- G1 – Minor: Small impact on power systems, slight aurora visibility in northern states.
- G2 – Moderate: Aurora possible in more mid-latitude states.
- G3 – Strong: Auroral activity reaches farther south but may be tough to spot without perfect conditions.
- G4 – Severe: Wide auroral visibility, including much of Connecticut during peak activity.
- G5 – Extreme: Rare and potentially disruptive; aurora can be seen across much of the continental U.S.
This week’s drop from G4 to G3 explains why Connecticut will miss out tonight. Even with clear skies over Bridgeport and Waterbury, the colorful glow just won’t stretch far enough south.
The Broader Impact of Solar Storms
Strong geomagnetic storms do more than paint the sky. They can mess with satellite communications, throw off GPS navigation, and cause headaches for power grids.
Connecticut sits close to major energy infrastructure in the Northeast. So, knowing about these storms isn’t just about chasing pretty lights — it’s also about being ready for whatever they might throw at us.
No Need to Worry Tonight
NOAA doesn’t expect any major disruptions from this storm. The main result? Local stargazers in Middletown and Meriden might just feel a bit let down if they were hoping for another round of glowing skies.
Researchers keep digging into solar activity, and forecasting tech keeps getting better. That means folks can look forward to improved heads-up for future sky shows.
Tonight, the real action’s up north—think Vermont, New Hampshire, and Maine. Still, if you’re in Connecticut and love the night sky, maybe keep your camera handy just in case.
The sun’s unpredictable cycles could bring more of those jaw-dropping auroras in the months or years ahead. When that happens, I bet towns all over the state will be ready to step outside and take it all in.
