A massive sunspot forming on the Sun's Earth-facing side has the potential to cause powerful solar flares.
Sunspot region 3089 is one of four sunspot regions being monitored for the possibility of a significant flare.
"This sunspot region was active a few days ago, but it has since quieted down significantly."
The presence of a magnetic delta structure indicates that it has the potential to produce an X-class flare, which is the most powerful type of flare.
According to Nasa, X-class flares are rare but can produce as much energy as a billion hydrogen bombs.
The current probability of an X-class flare from Sunspot region 3089 is 5%.
If it does make it to Earth, the resulting geomagnetic storm could harm satellites and communications infrastructure.
