Updated October 21, 20264 👨💻 The Sun is far from quiet: solar flares and other eruptions can seriously disrupt a technology-dependent world. Severe space-weather events can affect power grids, satellites, radio communications and navigation systems on Earth. This page tracks solar and geomagnetic…
A decaying sunspot nearing the Sun's western edge produced the strongest flare of the day, but the aurora chance for northern-tier states hinges on a separate stream of fast solar wind. Sunspot region AR4551 fired a moderate M-class solar flare early…
The northern lights may make an appearance in up to nine states Monday night, according to a forecast from the National Oceanic and Atmospheric Administration, which predicts mild auroral activity across the northernmost reaches of the U.S. A Kp index of…

Residents of many of the northern U.S. states, from Washington to Maine, could get a chance to see auroras around midnight. Aurora forecast: Solar wind could spark northern lights in Maine and other U.S. states on October 19-20 Skywatching enthusiasts are set to…
Oct 5, 2026 12:28 215 The cause comes from the Sun. As early as October 3, a coronal mass ejection reached the Earth, followed by a fast flow of solar wind. On October 4, it intensified the disturbances in the Earth's magnetic field to category G2, and…
The aurora borealis could potentially be visible from northern states like Alaska and Minnesota. Northern Lights Forecast: Here’s Where Aurora Could Be Visible Monday Night The northern lights could appear visible from states along the U.S.-Canadian border on Monday…
One of the more interesting aspects of the 1872 storm was that it likely originated in a medium-sized, but complex, sunspot group near the solar disk centre as confirmed by analyses of solar records from Belgium and Italy. These findings suggest…
The last ten days of October will be marked by a variable geomagnetic environment. Throughout the week, both relatively calm conditions in the geomagnetic field and periods of moderate to strong geomagnetic fluctuations caused by solar activity are expected.Detailed…
NOAA forecasts a minor geomagnetic storm on Tuesday between 5 and 8 a.m. Serbian time, driven by fast solar wind from a coronal hole. Sources do not assess visibility in Serbia. The Space Weather Prediction Center of the US agency NOAA has forecast…
