Several Russian cities had a fantastic light show last Thursday, as a bright meteor burst into a fireball over the landscape.
And once again, no one saw it coming until it exploded.
NASA's fireball records show that the meteor exploded with 2.8 kilotons of force on June 21 at 01:16 UTC over a number of Russian cities including Lipetsk, which is south-east of Moscow.
The explosion size correlates to a smallish asteroid of about 4 metres (13 feet) in diameter, which is a bit of a baby compared to the 20 metre (65 feet) asteroid that exploded back in February 2013 over Chelyabinsk, Russia.
