Cloud of plasma heading towards earth
A coronal mass ejection (CME) has broken off from the sun and is heading towards earth at a speed of 1200 km/second.
This comes after two flares were unleashed by the sun yesterday.
According to the South African National Space Agency, the second flare is the strongest in over a decade.
Sansa says the CME is expected to impact the earth in the early hours of tomorrow morning and could spark a geomagnetic storm.
"The impact of the CME will not harm humans at all or any other life forms on earth, explains SANSA's Catherine Webster, "however it can cause disturbances to our technology systems."
Webster says this includes satellites, communication systems, GPS navigation, the internet and DSTV.

The flares came from the sun's active region 2673.
The flares already impacted the earth's magnetic field on Wednesday resulting in "high frequency (HF) radio blackouts across the daytime side of Earth."
SANSA says it will continue to monitor the storm closely and issue regular alerts.
