Urgent Proposal for S-band Radar Observations of Binary Near-Earth Asteroid

1994 CJ1
ABSTRACT:
This is an urgent proposal requesting three hours of time between June 28 and July 3, 2014 (AST) to observe near-Earth asteroid 1994 CJ1. Recent continuous-wave Arecibo radar observations of this potentially hazardous asteroid have yielded double-peaked Doppler spectra strongly suggestive of a binary asteroid. 1994 CJ1 is one of the four smallest known binaries in the near-Earth asteroid population, and the smallest equal-mass binary known. We propose ranging and coarse-resolution delay-Doppler imaging observations that, in conjunction with ongoing optical lightcurve measurements, will constrain the nature of this system and its individual components.
