Radar Observations of Small Near-Earth Asteroids 2015 KQ120 and 2015 KM57

We request one 3.5-hour observing track (including transmitter warm-up time) to detect recently discovered near-Earth asteroids 2015 KQ120 and 2015 KM57. Asteroid 2015 KQ120 is an NHATS ob ject of interest to NASA as a possible future robotic or crewed mission target. Both asteroids are very small, expected to have diameters of roughly 10 to 30 meters, a size range poorly sampled by radar. Observations will refine the orbits and provide estimates of the size, spin, and surface characteristics of these small bodies. The requested time, 2015 June 4, 04:00-07:30 AST, is currently occupied by P1693 and X111 time. The transmitter could begin warming up during P2030, but ALFA would then have to be covered at 04:30.
