Halloween night turned out to be unexpectedly intense. Less than an hour ago—around 10 p.m. Moscow time—a G2-level geomagnetic storm began on a planetary scale.

According to incoming data, the planet is currently passing through a disturbed region of space. An increase in solar wind parameters is being recorded.

The forecast for a geomagnetic storm during the night from Friday to Saturday (https://xras.ru/image/kpf_RAL5_20261030.png) has been confirmed—it is now less than 24 hours away. The estimated start time has shifted slightly, from midnight to around 2–3 a.m.; however, in reality, the event could begin several hours earlier or later than that.

An eruption of a very large prominence, measuring about half a million kilometers, was captured today by the cameras of several space telescopes.

After a week of fluctuations, flare activity finally settled on a clear direction—downward—and plummeted to the bottom. The flare chart has effectively devolved into a smooth line, devoid of any signs of bursts.

According to the catalog, there is still one single sunspot remaining on the otherwise blank Sun today. However, it could not be found.

The "green streak"—a period of calm—continues, both on the Sun and here on Earth. Over the last 30 hours, there has been only one solar flare: a C1.1-level event, which occurred yesterday around 6:00 a.m. Moscow time.

There isn’t much happening on the Sun. The main point of interest remains whether the approaching coronal hole will be able to stir up Earth’s magnetosphere to any noticeable degree. Current calculations still indicate that the planet will enter a stream of fast solar wind as early as tomorrow, Wednesday, but they offer only very tentative predictions regarding the potential consequences.

Today is the most significant lunar day of October: the full moon. In strictly mathematical terms, the full moon occurred several hours ago—around 7 a.m. Moscow time—but it was difficult to witness that moment firsthand from within the country. Truly favorable conditions for viewing will only arrive this evening and tonight.

The geomagnetic situation has completely settled down over the past weekend, with a substantial margin of stability. The last faint disturbances—lingering effects from events earlier in the week—were observed on Friday. Both Saturday and Sunday were entirely "green" (calm), and the forecast for the next couple of days remains in the same "green" category.
