Asteroid trackers at NASA and elsewhere determined the rock to be about 2 metres wide.
An alert was sent to the Minor Planet Center in MA, and data was quickly relayed to NASA's Center for Near-Earth Object Studies at the Jet Propulsion Laboratory in California.
Preliminary data suggests that asteroid 2018 LA entered the atmosphere at roughly 15 kilometres/second (or 54,000 km/h) and released energy equivalent to a half-kiloton of TNT. Automated alerts were sent out to a community of asteroid observers worldwide, even as a communique was rushed to the Planetary Defense Coordination Office at the NASA Headquarters in the nation's capital.
Video posted on YouTube, from a farm just across the border in South Africa, showed a fireball swiftly descending and getting bigger, and then a blinding flash in the sky.More news: Amazon breaks Premier League hold of Sky and BT with streaming deal

'It is also only the second time that the high probability of an impact was predicted well ahead of the event itself'.
Tracing its potential zone of impact - not an easy task with only 14 observations - simulations found that it could have hit anywhere along a line that stretched from Oceania, all the way to southern Africa.
As per the calculations of the NEO watchers, the Asteroid entered the atmosphere in the region like Papua New Guinea to the Indian Ocean which is nearer to Africa.
Luckily for us, the asteroid was small, as mentioned above, and burnt up in the atmosphere without causing damages.
An asteroid four times as big exploded over Chelyabinsk, Russia, in 2013 in an airburst blowing out windows injuring more than 1,500 people mainly due to cuts caused by flying glass and debris. That said, it can never hurt to have more telescopes and eyes pointed at the sky looking for the next space rock aiming to knock on our door - or break it down.
In addition to monitoring the Earth, NASA also tracks the asteroids from space. The six feet (two meters) broad asteroid was discovered a few hours prior to reaching the Earth. However, the asteroid of 2008 was detected nineteen hours before it struck the sky over Sudan. The same asteroid hunter, Richard Kowalski, made all three discoveries.
