America's space agency NASA has reported on Tuesday an unusual explosion on the surface of the Sun, which according to the US National Weather Service (NWS) released a solar flare that would likely disrupt satellite, communication and power facilities on Earth over the next two days.

The NWS added in its statement that a similar explosion of the same magnitude occurred five years ago, with the present one measured by NASA as M-2 or medium sized solar flare that carries "a substantial coronal mass ejection (CME) ... and is visually spectacular."

NASA said in a statement that the observed solar flare reached its peak at 0341 AEST on Tuesday, in which "the large cloud of particles mushroomed up and fell back down looking as if it covered an area of almost half the solar surface."

That spontaneous solar activity, however, is expected to cause minimal effect on Earth since the impact of the explosion will not directly travel towards the planet's direction.

At most, the NWS said that the eruption will likely bring minor (G1) to moderate (G2) levels of geomagnetic storm activities, which could disturb Earth's power grids and global positioning systems that heavily rely on satellite communications.

NASA said that the explosion's soft impact is estimated to reach Earth at around 0400 AEST on Wednesday and may force airlines to adjust plane schedules that will pass on the polar regions, where much of the effect will be concentrated.

Bill Murtagh, senior program coordinator at NWS, described the solar explosion to ABC as "rather dramatic ... but wasn't that big ... we got energy particle radiation flowing in and we got a big coronal mass injection."

Murtagh added that basing on their observation, the whole solar eruption yesterday was "visually spectacular ... and you can see all the materials blasting up from the Sun so it is quite fantastic to look at."

Despite NASA's conclusion of 'fairly small' effects on Earth, the Space Weather Prediction Centre of NWS said that it will continue its monitoring of the event, which is expected to cause some friction on the magnetic fields of both the Earth and Sun.
