Крупнейший солнечный протуберанец вызвал магнитную бурю уровня G1 на Земле

G1-level geomagnetic storm occurred on Earth on December 17

On Tuesday, December 17, a brief G1-level geomagnetic storm was recorded on Earth, triggered by a solar ejection on Sunday, December 15.

According to the Solar Astronomy Laboratory of the IKI and ISZF RAS, the prominence ejected by the Sun partially affected Earth in the morning, causing a geomagnetic disturbance peaking at 6:00 AM Moscow time. The storm ended quickly, but the Sun's plasma is still near the planet, which may lead to minor local bursts.

The IKI RAS reported that the ejection of one of the largest solar prominences of 2024 occurred on December 15. This structure, visible in images of the Sun's southern hemisphere as early as December 14, disappeared from subsequent images. The length of the prominence exceeded half a million kilometers, making its scale impressive even by the Sun's standards.

A G1-level storm is considered the weakest on a five-point scale, where the maximum level G5 can cause serious disruptions in power grids, satellite systems, and radio communications.

No new geomagnetic storms are expected in the near future, although minor geomagnetic disturbances are possible on January 5 and 10.

Mikhail Leus, a leading specialist at the Phobos weather center, noted that the storm on December 17 was a result of a fast solar wind. He also warned weather-sensitive people about possible headaches and blood pressure spikes during such periods.

Tatyana Machneva, Head of the Department of Physics and Mathematics at the Pirogov Russian National Research Medical University, emphasized that the impact of geomagnetic storms on human health has not been scientifically confirmed. However, weather-sensitive people, especially those with cardiovascular diseases, may experience general malaise.
