G1 Magnetic Storm on the Night of November 7: NOAA Forecast and Health Impacts

By the end of the week, the geomagnetic situation on Earth may change significantly. After a relatively calm period, experts are forecasting an increase in activity linked to solar wind. According to data from the NOAA Space Weather Prediction Center released on November 5, 2026, the most noticeable fluctuations are expected ahead of the weekend and directly on Saturday, making this night a focal point for observing space weather.

What NOAA is Forecasting

Experts predict high geomagnetic activity on the night of November 6–7, 2026. In Kyiv time, a Kp index of 5 is expected from approximately 02:00 to 05:00 on Saturday. This means the peak of magnetospheric disturbance will occur in the early morning hours of the weekend, after which the activity is expected to subside, according to the current forecast.

How the Kp Index Works

As explained by the German Research Centre for Geosciences (GFZ), the Kp index characterizes the degree of Earth's geomagnetic activity. The index is determined based on data from ground-based observatories during three-hour intervals, with a scale ranging from 0 to 9. Values below 5 are not classified as magnetic storms, while values of 5 and above correspond to G1–G5 storm levels: G1 is the lowest of these, and G5 denotes an extreme geomagnetic storm.

What the G1 Level Means

According to the classification by the UN Office for Disaster Risk Reduction, G1 level disturbances may cause minor fluctuations in power grids and affect satellite operations. Polar lights may also be visible at high latitudes during such events. Thus, the activity expected on the night of November 7 falls at the lower threshold of the storm range and does not imply serious technological consequences.

Does a Magnetic Storm Affect Health?

Regarding human well-being, there is insufficient conclusive evidence of a direct impact of geomagnetic fluctuations on headaches, blood pressure, or sleep. The United States Geological Survey (USGS) notes that Earth's magnetic field does not directly affect human health. Therefore, health issues should not be automatically attributed to space weather: if unusual or pronounced symptoms appear, it is important to seek their true cause rather than attributing them to the geomagnetic background.
