Saffas only had a moment to feel slighted by the sky on Friday, when folks from across Europe, in the United States and as far as New Zealand began sharing images of colourful Northern Lights (Aurora Borealis) sightings.
While we all freaked out about our WhatsApp messages from the North, the sky above South Africa was getting supercharged.
Then, we were treated all the same to a show of the elusive Southern Lights, or the Aurora Australis. If you didn’t manage to catch them in real time, don’t worry, we’ve got you. There are a bunch of cool images taken by Saffas at home and spread across the world, who joined the global responses to the historic solar storm that impacted Earth this weekend.
Night skies were lit up by these bright colour lights in locations where they don’t normally shine as a severe solar storm supercharged the phenomenon.

Friday’s storm was the first severe geomagnetic storm watch issued since 2005, reaching intensity G5 on a 1-5 scale on Saturday in the Northern hemisphere, making it the strongest storm to reach Earth’s atmosphere since October 2003’s “Halloween Storms,” said Bryan Brasher, National Oceanic and Atmospheric Administration’s Space Weather Prediction Center spokesperson via NBC News.
According to the South African National Space Agency (Sansa), the storm happened throughout the night on Friday and continued into Saturday, per TimesLIVE.
Sansa’s Space Weather Centre issued several G4 warnings and, for the first time since 2003, one G5 warning was issued. These are readings on the geomagnetic storm scale that indicates the severity of geomagnetic storms, rated from 1 to 5, with 1 a minor event and 5 an extreme event.
According to Vaneshree Maharaj, a spokesperson for the agency, a solar storm happens when charged particles emitted by the sun collide with Earth’s magnetic field. Typically, the effects are limited to technological systems, manifesting most visibly as the auroras in the northern and southern hemispheres.
“We haven’t seen anything like this since about 2003. The beautiful spectacles you see happen when protons, neutrons and electrons in the air all react differently and glow strange colours,” she said, explaining why some parts of the planet saw different colours in the sky.
“Normally it’s confined to the North and South poles, but because this one was so substantial people saw it spreading out towards the middle of the planet. Had the G5 storm grown worse or continued for longer I think we might have been able to see something in Gauteng.”
Then again, people in bigger cities, like London, won’t really be able to see something so special because light pollution tends to cancel out the brightness of the coloured lights.
