Goldstone Radar Posted Images of (7753) 1988

Goldstone Radar posted Delay-Doppler images of (7753) 1988 obtained on November 18-22, 2020 which shows an elongated object with distinct surface features rotating slowly with time. JPL Orbital parameters show that 7 doppler radar observations were used to update the orbit. JPL solution date: 2020-Nov-24 05:23:52
