Strong solar flares could be released from a large sunspot that is growing on the Earth-facing side of the Sun.
Astronomers have issued a warning about the potential for widespread disruption.
One of four sunspot regions being watched that have a significant flare potential is sunspot region 3089.
despite the fact that it is the only one capable of causing a strong geomagnetic storm to develop in the Earth's atmosphere.
This sunspot area was busy a few days ago, but it has now become much quieter. It is notable because it has a magnetic delta structure.
The most recent report from SpaceWeatherLive, which monitors solar and auroral activity in real-time, mentioned the sunspot region.
It has the potential to produce an X-class flare, which is the largest sort of flare, because there is a magnetic delta structure there.
