A sunspot blasting magnetic radiation could see a solar flare develop and make its way towards Earth.
Scientists fear a solar flare could be building up from the sunspot.
The sunspot has been catalogued as AR3089 and has been described as mellow, but scientists say it has developed a magnetic field that can harbour energy for solar flares.
Former NASA astronomer Dr Tony Phillips wrote on SpaceWeather.com : "Could it be the calm before the storm?”
He added: "It has developed a delta-class magnetic field that harbours energy for X-class solar flares.”
The X-class is the strongest class of flare and it can produce as much energy as a billion hydrogen bombs.
Solar blasts, also known as a Coronal Mass Injection (CME), are very common and not all of them travel towards the Earth, but when they do - they have the power to be disruptive.
They do not pose a direct threat to us as Earth's atmosphere stops the radiation.
The latest forecast from NOAA’s Space Weather Prediction Center predicts there is a five per cent chance that an X flare will happen in the next three days.
Scientists say the sun is heading toward the peak of its 11-year sunspot activity cycle, meaning this star will stay hyperactive for the next few years.
Some flares can reach speeds of between 250km-3,000km a second, according to the US Space Weather Prediction Center (SWPC).
Issues can also be expected for amateur radio and GPS systems, particularly near dawn and dusk.
CMEs are powerful eruptions of plasma on the Sun's surface.
Billions of tons of material are lifted off the surface and can explode away from the Sun with the force of around 20 million nuclear explosions.
Scientists don't quite yet understand what causes CME's, but do believe that it is something to do with the Sun's magnetic field.
EarthSky.org explained: "Because the sun is a fluid, turbulence tends to twist the magnetic field into complex contortions. Twist the field too much, and it kinks, much like a phone cord or toy Slinky.
"These kinks snap the magnetic field and can potentially drive vast amounts of plasma into space."
In 1989, a strong solar eruption shot so many electrically charged particles at Earth that the Canadian Province of Quebec lost power for nine hours.
