"On October 8, 2009 about 03:00 Greenwich time, an atmospheric fireball
blast was observed and recorded over an island region of Indonesia. The
blast is thought to be due to the atmospheric entry of a small asteroid
about 10 meters in diameter that, due to atmospheric pressure, detonated
in the atmosphere with an energy of about 50 kilotons (the equivalent of
110 million pounds of TNT explosives)."
Missed this when it initially happened.
