During the last few days, including today, the Sun has had higher geomagnetic activity and several strong coronal mass ejections are approaching the Earth. One of them should arrive tonight or tomorrow morning and cause the aurora borealis. The good news is that the eruptions on the Sun have been so strong that there is a good chance that we could see the aurora borealis at our latitudes.

The ejected material is currently heading towards Earth in several waves, but it is impossible to determine in advance how strong the aurora might be and when it will be visible. https://twitter.com/CHMUCHMI/status/1788834833998676220 According to the Czech Hydrometeorological Office (ČHMÚ), today will also be ideal conditions for monitoring, as the sky should be clear without much moonlight. If you want to see the aurora borealis, head outside the illuminated city and focus on the northern horizon.
According to space.com, a dark spot on the Sun named AR3664 has grown in size over the past few days, becoming the most active of the sunspots in this cycle. Already at the beginning of this week, scientists expected higher activity, and the prediction came true. The giant sunspot has released several X-magnitude eruptions, the most powerful, in recent days. This is followed by M, C, B and A class eruptions, with A being so weak that it no longer has any effect on Earth.
The aurora occurs when ejected solar material reaches Earth and begins to interact with the magnetic field. This is strongest in the polar regions, which is why the phenomenon is called the aurora borealis. However, during strong eruptions, it can also be observed in other areas. We usually see it as green streaks moving across the sky. But it can also appear in pink, red and even burgundy.
