ESA astronomers have determined that the object [WT1190F] will impact the Earth on November 13, 2015 at approximately 06:20 UTC (11:50 local time), south of Sri Lanka. Due to its small size, it is expected that most or all of the object will burn up in the atmosphere before impacting, but will be visible as a bright daytime fireball.

WT1190F is probably the same object as 9U01FF6

9U01FF6 is probably less than a metre in diameter.

(If it were an asteroid then with H = 30.6, it would be 2-5 metres wide)
