Asteroid 2009 DS36 was discovered from Calar Alto Observatory (Spain) in the morning of February 25th 2009. Its fast motion on the sky suggested that it had to be located not too far away from Earth and indeed the preliminary orbit shows that this is a Near-Earth Object (NEO), the first object of this class discovered from Calar Alto. Its estimated diameter is around 15 meters.
