Bistatic delay-Doppler image from Sep. 7.  Resolution is 3.75 m x 50 Hz.  This is a 16-second integration that spans one full rotation by the asteroid.  The asteroid rotates so rapidly and it's so small that the radar images do not show any detail.  Range increases downward and Doppler frequency increases to the right. At the time of the observations, the asteroid was slightly more than one lunar distance from Earth.
