Proposal Title: Arecibo Radar Observations of 21 Near­Earth Asteroids During February­August
2012
ABSTRACT:
We request 75 sessions (163 hours observing + 75 hours setup = 238 hours total) to observe 21 Near­Earth
Asteroids, 8 of which are likely larger than a kilometer, 7 of which o#er opportunities for shape modeling at high
signal­to­noise ratio (>1000/day), a few of which may be binaries, and several of which may reveal
non­gravitational perturbations such as the Yarkovsky e#ect. Not much is known about the majority of the objects
in this sample. Our goals include detailed physical characterization, determination of binarity or multiplicity,
orbital refinement, and shape modeling when possible.
