Solar flare prompts storm warnings, chance at seeing the northern lights this week
NOAA said the storm could reach G3 strength and bring auroras as far south as Oregon, Iowa and New York.
- NOAA's Space Weather Prediction Center issued a geomagnetic storm watch for Monday and Tuesday, citing the "anticipated arrival of the CME that left the Sun" on Saturday.
- When CMEs collide with Earth, they create geomagnetic storms measured on a scale similar to hurricanes; the SWPC linked this week's watches to a solar flare and associated CME from the weekend.
- G3-Level storms, associated with an index of 7, could bring the northern lights as far south as Oregon, Wyoming, Iowa, and New York; forecasting from the University of Alaska Fairbanks suggests visibility reaching Kansas, Missouri, Kentucky, West Virginia, and Maryland.
- While storms can cause "immediate, weak degradation to high frequency communication bands," impacts are "but usually mitigable." Peak daytime activity may be blocked by sunlight, limiting visibility to camera-assisted viewing.
- Forecasting space weather remains challenging, and conditions might not be strong enough to spark widespread auroras; additional details will emerge as the material moves closer to Earth on Monday.

Geomagnetic storm watch issued, but could Northern Lights be visible in Chicago?
A geomagnetic storm watch has been issued for the early stages of the week, but could the Northern Lights be visible in the Chicago area? The NOAA’s Space Weather Prediction Center has issued a Class G3 geomagnetic storm watch for Monday night after a coronal mass ejection from the sun over the weekend, sending charged particles hurtling through space and toward the Earth. Once those particles interact with Earth’s magnetosphere, it could cause …

A CME is an exp…
A Solar Storm Is Heading Towards Earth; Amazing Light Can Be Seen Across the World, Including India.
An explosion on the Sun's surface is causing a strong magnetic storm to approach Earth. Its effects are expected to cause the Northern Lights (aurora) to appear in northern India.
Solar flare prompts storm warnings, chance at seeing northern lights in Oregon this week
Days after Earth was impacted by several coronal mass ejections, forecasters say a recent solar flare could be directed at us, potentially sparking another chance at the northern lights.
