Strong Geomagnetic Storm Watch issued as sunspot energy heads toward Earth
- NOAA issued a strong Geomagnetic Storm Watch after multiple eruptions occurred on the sun Sunday.
- These eruptions, called coronal mass ejections , consist of charged solar plasma and magnetic fields.
- The CMEs are expected to impact Earth's upper atmosphere, potentially producing aurora borealis as far south as Oregon.
- A shock from one or more CMEs arrived just before 11 a.m. PDT; the Kp index forecast shows 5 to 6.
- Resulting geomagnetic activity may cause minor effects on technology, but the aurora borealis could be visible in remote areas.

Major solar storm could bring the Northern Lights to New York — and chaos to satellite systems
A strong geomagnetic storm unleashed by multiple magnetic eruptions on the Sun means many Americans in the Lower 48 could be treated to quite a spectacle late Tuesday night and early Wednesday morning.

Strong geomagnetic storm could bring northern lights to multiple states: forecast
(NEXSTAR) — Skywatchers across at least 18 states may have the chance to see the northern lights on Tuesday as a coronal mass ejection impacts Earth. NOAA's Space Weather Prediction Center has been tracking the coronal mass ejection, or CME, since Sunday. Tuesday morning, the SWPC said early signs pointed to the CME barreling through space "in the general direction of Earth." "This raises our measure of confidence in a geomagnetic storm," the SW…
