A mysterious bright green light was seen streaking over Johor Bahru's sky in the wee hours of the morning last week
The light was seen hurtling across the dark sky, blazing brightly before it vanished just as quickly as it appeared.
The five-second phenomenon was caught on YouTube user Crystal's dashcam as she was driving in Johor Jaya at 5am last Wednesday, 12 February.
The footage, uploaded to social media and YouTube, has since gone viral with people wondering what the green flash could be
These two Facebook users think its Superman or Green Lantern who have landed in Malaysia.
While another netizen joked, "[It's like in] Shaolin Soccer. That year he kicked the ball into the sky... It just fell back."
Meanwhile, a Street Fighter fan said, "That looks like Ryu's Hadouken. He's probably fighting against Akuma again."
Other comments revealed that Crystal wasn't the only one who chanced upon the special sighting
Sharing her YouTube video in a Johor Bahru-based Facebook group, someone replied with their own dashcam footage of the bright light shooting down from the sky at the same time on the same day, except it appeared to be blue.
Meanwhile, in a Singaporean Facebook group, someone commented that they saw the same thing in Loyang, eastern Singapore, at exactly the same time.
"I saw this at Loyang at 5am! Same time stamp! I thought Singapore was under attacked (sic)! Thank God it wasn't a hallucination," the Facebook user said.
But based on the multiple reported sightings, it was deduced that the bright light in the sky is most likely a fireball
According to the International Meteor Organisation (IMO), a fireball is a very bright meteor, and these are usually tiny fragments of stone, ice, or metal orbiting from outer space that entered the Earth's atmosphere.
The organisation, which collects meteor sightings from all over the world, said that the brightest fireballs are fragments just larger than 1 millimetre and actually occur every day, but remains a rare sight because they can happen over oceans and uninhabited land or even in broad daylight.
According to IMO, last Wednesday, there were seven others who witnessed the fireball from this part of the world
Based on reports by the individuals from Johor Bahru and Singapore, the fireball had lasted between three to seven seconds in the sky and appeared green, blue, white, orange, and even pink to them.
"It exploded into a huge fireball of orange, red colour," reported a May Lilian from Johor Bahru, "I really saw it exploded right in front of me. It felt super near as I was standing on my balcony watching it appear and disappear within seconds."
"Stunning when I first saw it," wrote Mini, a Singaporean, who also commented that she saw the fireball light the night sky pink.
The American Meteor Society explains that the dominant composition of a meteoroid plays an important part in the observed colors of a fireball. For example, when vaporised, sodium produces a bright yellow colour, nickel shows green, and magnesium glows blue-white.
The fireball could have produced different colours while flying across the sky because of its mixed chemical composition.
