What is a coronal mass ejection (CME)?
A CME is a large eruption of plasma and magnetic field from the sun.

Get ready for a potential celestial show! A geomagnetic storm watch has been issued, raising the possibility of vibrant Northern Lights displays across a large portion of the U.S. and Canada during the Labor Day weekend. This phenomenon is...
### Geomagnetic Storm Watch in Detail
A geomagnetic storm watch has been issued due to a coronal mass ejection (CME) observed on August 30th. This CME is classified as a "full halo," meaning it expanded outward from the sun in all directions. When it reaches Earth, it's expected to cause geomagnetic storming.
NOAA's Space Weather Prediction Center (SWPC) anticipates the storm to reach G2 (moderate) levels on Monday evening, potentially intensifying to G3 (strong) overnight into early Tuesday.
### Visibility Forecast
The highest chance of seeing the Northern Lights is across northern Canada and Alaska. However, states like Washington, Oregon, Idaho, Montana, Wyoming, North Dakota, South Dakota, Nebraska, Minnesota, Iowa, Wisconsin, Michigan, Illinois, New York, Vermont, New Hampshire, and Maine also have a good chance of witnessing the aurora. The UK Met Office also suggests possible visibility as far south as East Anglia, the Midlands, and Wales.
### How to Prepare
1. **Find a Dark Spot:** Get away from city lights for the best view. 2. **Check the Timing:** The best viewing time is typically between 10 p.m. and 2 a.m. local time. 3. **Monitor Conditions:** Keep an eye on NOAA’s SWPC forecasts for updates. 4. **Use a Camera:** Capture the lights with a wide-angle lens, or use your smartphone's night mode with a tripod.
### Who This Affects Most
This event primarily affects those in northern latitudes, offering a chance to see the aurora. However, strong geomagnetic storms can also impact satellite operations and power grids, potentially affecting broader regions.
Historical Context: Solar activity is expected to peak in early 2026, so this is a part of a broader trend.
A CME is a large eruption of plasma and magnetic field from the sun.
The G-scale classifies geomagnetic storm intensity from G1 (minor) to G5 (extreme).
When one CME sweeps up another in space, scientists call it a "cannibal CME".
