Recent solar activity, including a coronal mass ejection, may lead to visible northern lights across parts of the U.S. on Monday and Tuesday. The NOAA has issued geomagnetic storm watches, with potential impacts on technology and communication, depending on the storm's strength.
- 01A G3 geomagnetic storm watch is in effect for Monday, and a G2 watch for Tuesday, due to a recent solar flare and coronal mass ejection.
- 02The Kp index, which measures geomagnetic storm strength, could peak at 7, allowing for northern lights visibility in northern states.
- 03If conditions are favorable, the aurora may be visible as far south as Oregon, Wyoming, Iowa, and New York during the evening hours.
- 04Forecasts suggest that the aurora may only be seen on the northern horizon in states like Kansas, Missouri, and Kentucky with technical support.
- 05The NOAA emphasizes that while solar activity is common, significant impacts on infrastructure are usually manageable.

Following several coronal mass ejections from the Sun, a recent solar flare has prompted the NOAA's Space Weather Prediction Center to issue geomagnetic storm watches for Monday and Tuesday. The expected G3 storm could allow the northern lights to be visible in northern U.S. states, depending on the storm's strength and nighttime conditions. The Kp index, which gauges geomagnetic activity, is forecasted to peak at 7 on Monday afternoon, but the aurora may be obscured by sunlight at that time. However, as the Kp index drops to 6.3 later in the evening, visibility could improve, potentially allowing sightings as far south as Oregon, Wyoming, Iowa, and New York. Forecasts from the University of Alaska Fairbanks suggest that under the right conditions, the aurora may even be seen on the northern horizon in states like Kansas and Missouri. While solar activity can affect technology, the NOAA notes that impacts are generally manageable and further updates will be provided as the CME approaches Earth.
