Geomagnetic storms today

On Friday, January 16, 2026, a kIndex of 3 indicates a quiet level of geomagnetic activity. This index measures the fluctuations in the Earth’s magnetic field caused by solar wind and other solar phenomena. A kIndex of 3 signifies minor disturbances which are generally imperceptible to the average person and do not typically result in noticeable effects on daily life or technology. However, for weather-sensitive individuals, such as those with certain medical conditions, the psychological and physical impact can vary. Some individuals report heightened sensitivity to changes in geomagnetic conditions, which may manifest as slight mood fluctuations, fatigue, or headaches. Although these responses are often anecdotal and not universally experienced, it's important for affected individuals to remain mindful of their well-being during periods of geomagnetic activity. Overall, a kIndex of 3 suggests minimal disruptions, allowing most people to carry on with their daily activities without significant concern.
