NOAA’s Space Weather Prediction Center issued a moderate G2 Geomagnetic Storm Watch for Monday. Moderate Northern Lights activity is likely beginning Sunday night into Monday morning, with the potential to see the lights as far south as southern Wisconsin and northern Nebraska.
Geomagnetic storm triggers vivid display of Northern Lights across the North Friday
Skies lit up in jaw-dropping colors across North Dakota as a strong geomagnetic storm struck the Earth’s atmosphere early Friday morning.
A series of eruptions from the Sun continue to send plasma blasting toward Earth, causing NOAA’s Space Weather Prediction Center (SWPC) to issue another Geomagnetic Storm Watch and creating vivid Northern Lights displays across parts of the U.S.
The SWPC issues geomagnetic storm alerts to warn of potential interference with communication systems and spacecraft operations. During significant solar storms, widespread power outages are possible, and communication systems are subject to failure. Solar wind causes the reactions in Earth’s atmosphere that create the Aurora Borealis or Northern Lights. Intense space weather events can cause Aurora lights to appear farther away from Earth’s poles, as they did last week.
WHAT ARE THE 5 CATEGORIES THAT MEASURE GEOMAGNETIC STORMS?
This latest Geomagnetic Storm Watch has been issued for Monday and Tuesday because of a coronal hole high-speed stream, or CH HSS. The SWPC issued a moderate G2 Geomagnetic Storm Watch for Monday as a fast solar wind associated with the CH HSS is expected to arrive early Monday to midday. Minor G1 levels are likely through Tuesday, according to NOAA.
