Space weather forecasters are keeping a close eye on a powerful solar eruption that may bring a dazzling show to the night sky across Delmarva, along with the potential for minor disruptions to technology here on Earth.
Earlier today, the NOAA Space Weather Prediction Center (SWPC) confirmed a fast-moving coronal mass ejection (CME) associated with an intense X5.1-class solar flare that blasted off the Sun from active Region 4274. This marks the strongest flare yet from that sunspot group, and one of the most energetic solar events of the year.
Preliminary analysis shows the CME is racing toward Earth at extraordinary speeds, with shockwave estimates near 4.4 million miles per hour. Forecasters believe the leading edge could impact Earth as early as late tonight, November 11th, continuing into the early morning hours of November 12th.
What This Means for Delmarva
While current projections indicate the CME may not be perfectly directed toward Earth, there still appears to be enough of a direct component to trigger strong geomagnetic storm conditions. SWPC experts are evaluating whether a G4 Watch (a category representing severe impacts) will be needed.
Under these conditions, residents across Delmarva may have the chance to witness the Northern Lights, an opportunity that’s becoming more frequent as the Sun approaches the peak of its 11-year solar cycle.
Auroras could become visible tonight after dark, especially if skies remain clear and the geomagnetic field responds strongly.
Viewing will be best:
- Away from city lights
- With a clear north-facing view
- During peak storming windows expected from 11 PM to 3 AM
Even smartphone cameras may capture the aurora better than the naked eye thanks to long-exposure capabilities.
Potential Impacts
Geomagnetic storms of this magnitude can cause:
- GPS inaccuracies
- High-frequency radio disruptions
- Voltage fluctuations on power grids
- Impacts to satellites and spacecraft operations
Airline routing over polar regions may also be adjusted during peak activity to maintain communications reliability.
The SWPC emphasizes that this situation remains fluid, and forecasters will continue refining projections as new data arrives.
Stay Alert for Updates
Residents are encouraged to monitor official forecasts tonight, especially if you’re hoping to catch a rare aurora show right here in the Mid-Atlantic.
