A new weak magnetic storm is forecast for Earth today, November 16. The British Geological Survey reports that the speed of the solar wind is gradually decreasing after the impact of several coronal mass ejections, but conditions in the space environment are still disturbed.
Scientists warn that the probability of increased geomagnetic activity remains, but the storm will be small - at the G1 level, that is, the lowest on the magnetic storm scale. Such events usually cause minimal disruption to communication and navigation systems and affect the well-being of only sensitive people.
The Sun has been experiencing some of its most intense activity this year in recent days. According to space.com, the X5.1-class flare that occurred on November 12 was the most powerful in 2025 and caused noticeable radio interference in Africa and Europe. The radiation from this flare reached Earth almost instantly.
The largest solar plasma ejection was recorded on November 11 — the largest event since the strong October 2024 flare. The consequences affected high-frequency communications on the dayside of the planet: radio signal attenuation and short-term communication losses were observed in some places.
Prior to this, on November 9 and 10, the same active solar region experienced a series of smaller but intense flares accompanied by coronal mass ejections. These also reached Earth and caused large-scale auroras at higher latitudes.
Experts emphasize that although the current storm will be weak, a period of increased solar activity continues. In the coming weeks, new flares and plasma emissions are possible, which could affect space weather and cause oscillations in the Earth's magnetosphere.
