When to Expect Magnetic Storms: A Weekly Calendar of Solar Activity

The intensity of the geomagnetic storm that has been affecting Earth for an extended period has begun to decrease. Meanwhile, astrophysicists predict minor solar activity for the upcoming week.

"Telegraph" will inform you about when to expect geomagnetic storms next week, referencing data provided by the Space Weather Prediction Center (SWPC) of NOAA.

It is important to note that geomagnetic activity is measured on a scale from 0 to 9. The planetary K-index is used for this measurement, where a reading of 5 or higher indicates a strong geomagnetic storm.

Geomagnetic Storms on January 20

On Monday, January 20, solar activity is expected with a K-index of 4 (yellow level), corresponding to minor geomagnetic storms.

Geomagnetic Storms on January 21

On Tuesday, January 21, solar activity is anticipated with a K-index of 3 (green level), indicating weak geomagnetic storms.

Geomagnetic Storms on January 22

Forecasts suggest that on January 22, 2025, low solar activity will occur with a K-index of 3 (green level), which signifies weak geomagnetic storms.

Geomagnetic Storms on January 23

According to forecasts, on January 23, 2025, low solar activity is expected with a K-index of 2 (green level). This indicates the absence of significant geomagnetic storms.

Geomagnetic Storms on January 24

On January 24, 2025, low solar activity is anticipated with a K-index of 2 (green level). This means that geomagnetic storms will be minor.

It is important to note that geomagnetic storm forecasts may change, as solar activity researchers update their data every three hours. Therefore, we recommend keeping an eye on these changes regularly. All current information regarding geomagnetic storms can be viewed below.

What is a Geomagnetic Storm

A geomagnetic storm is a phenomenon caused by continuous flares and explosions on the Sun, resulting in the release of a significant amount of solar energy. It consists of charged particles (protons and electrons) that move rapidly in various directions, including towards Earth. When they reach Earth's magnetosphere, an activity occurs that scientists refer to as geomagnetic storms or solar storms.

To differentiate geomagnetic storms, a power level index known as K-indices is used. Fluctuations in the range of K-index 1 to K-index 4 are considered minor and often go unnoticed by Earth's inhabitants. Any geomagnetic storms exceeding a K index of 5 are classified as red-level storms. Additionally, during high-level geomagnetic storms, communication sources such as cell towers, satellites, radio frequencies, and GPRS may experience disruptions. During geomagnetic storms reaching K-index 7 or 8, auroras can be observed.
