On Twitter #UFO was trending as a variety of posts about the odd sightings went up.
The scene was so bizarre some even questioned if it was a portal or wormhole opening in the sky from another dimension.
One UFO spotter said: “This was all over Twitter a few hours ago.
“A few people posted sightings of this green glowing disk over South Africa.
“It was at the Cape of Good Hope, over Cape Town.
“In the enlargement I made, you can clearly make out its disk shape and glowing bottom centre.”
The poster claimed it was a UFO he saw three years ago returning.
He said: “I once reported such a metallic disk over Cape Town about three years ago.
“I found it on Google Earth map, but after making a video and reporting it on my site, Google did delete it from their map within 2-3 months.
“This UFO today, looks like the same craft.”
