The space agency has noticed that a hole in the sun’s atmosphere, known as a coronal hole, has begun “crackling”.
The hole is not facing towards Earth but as our planet and the sun rotate, the coronal hole could line up with us.
A video from NASA shows solar flares are beginning to simmer.
But by the time the hole face Earth, the solar flares could have become much stronger.
Any potential solar storm is classified as a relatively weak B-class, but researchers warn that it could become more powerful in the coming days as our host star heads into the solar minimum.
The sun follows cycles of roughly 11 years where it reaches a solar maximum and then a solar minimum.
During a solar maximum, the sun gives off more heat and is littered with sunspots. Less heat is given off in a solar minimum due to a decrease in magnetic waves.
A statement on the website Space Weather reads: “Such relatively weak flares would never be mentioned during Solar Max, but any flare is remarkable during the current period of deepening Solar Minimum.
“In the next day or so, the underlying sunspot will be revealed by solar rotation, and we shall see if it has potential for stronger explosions.”
If the solar flares do become more powerful in the coming days as the sun releases some of its last batches of heightened magnetic waves, it could be devastating for technology on Earth.
For the most part, the Earth’s magnetic field protects humans from the barrage of radiation, but solar storms can affect satellite-based technology.
Solar winds, which are a stream of particles from the sun, can heat the Earth’s outer atmosphere, causing it to expand.
This can affect satellites in orbit, potentially leading to a lack of GPS navigation, mobile phone signal and satellite TV such as Sky.
Additionally, a surge of particles can lead to high currents in the magnetosphere, which can lead to higher than normal electricity in power lines, resulting in electrical transformers and power stations blow outs and a loss of power.
The higher amounts of radiation also leave people vulnerable to cancer.
