[Regnum] Solar activity continues to increase. At midnight, an M3.6 solar flare was recorded, the strongest since October 10. This event is fairly average, but stands out against the backdrop of the almost complete absence of flares over the past month. This was reported on the Telegram channel by the Laboratory of Solar Astronomy (XRAS).
The explosion's location is not far from Earth, so the ejected plasma clouds could reach Earth. However, nothing of the sort is visible yet, experts explained.
"We'll see, but at first glance, the Sun currently has the energy for single explosions, but certainly not for a series of flares. The cluster is relatively small in area, about 300 units, but it belongs to the highest complexity class, so surprises are generally possible. If this is indeed a series, it will become apparent in the coming hours," the laboratory warned.
One of the largest coronal holes this year, measuring approximately one million kilometers across, has been discovered on the Sun. It could trigger magnetic storms on Earth that will last several days. According to experts, the solar wind stream from the discovered coronal hole will reach Earth on the night of November 6-7. The first noticeable magnetic storms could begin as early as the night of November 7, and the stream's effects will last for at least five days.
On October 31, a G2 magnetic storm occurred on Earth, caused by the prolonged impact of a plasma flow from a coronal hole. Prior to this, on October 11, scientists recorded a G3 magnetic storm, the strongest in the past three months.]

Scientists warn of magnetic storms due to a giant hole in the Sun.
One of the largest coronal holes this year, measuring approximately one million kilometers across, has been discovered on the Sun. It could trigger magnetic storms on Earth that will last several days, the press service of the Solar Astronomy Laboratory at the Space Research Institute of the Russian Academy of Sciences reported on November 5
In the images, the coronal hole appears as a huge dark region. Scientists explained that this is a region of the solar atmosphere where the temperature and plasma density are significantly lower than in the surrounding regions. Therefore, it emits less light and appears black.
Plasma streams erupt from these regions into space, reaching speeds of several hundred kilometers per second. When they reach Earth, they affect its magnetic field and can trigger magnetic storms.
According to experts' calculations, the solar wind stream from the discovered coronal hole will reach Earth on the night of November 6-7. The first noticeable magnetic storms could begin as early as the night of November 7, and the stream's impact will last for at least five days.
Scientists cannot yet accurately predict the intensity and duration of magnetic storms, as the actual characteristics of the solar wind will only become known as it approaches Earth. Depending on these characteristics, it is possible to experience either isolated short-term disturbances or several days of virtually continuous magnetic storms. Complete stabilization of the geomagnetic situation is not expected before November 13-14.
