Proposal Title: Arecibo Radar Observations of Nineteen Near­Earth Asteroids During October
2011­January, 2012
ABSTRACT:
We propose to observe 19 near­Earth asteroids via S­band. Due to a high number of exciting objects in period
from Oct 2011 to Feb 2012, we propose an ambitious schedule of 153 hours of observing time. Asteroid 2005
YU55 stands out as once­per­decade radar target. This ” 400 m diameter object will be at 0.85 lunar distances (LD)
on Nov 8, 2011 and the radar data quality will truly be comparable to a spacecraft flyby. Another outstanding
target coming in mid­October is Ganymed, which at 40 km diameter is the largest near­Earth object. In the case of
Ganymed, we are particularly interested in satellite search. The third highlight is a binary asteroid 1996 FG3 that
has been mentioned as the target of interest for the future space missions. We are also very interested in
observing asteroids that have been scheduled as targets in the complementary programs such as Spitzer Space
Telescope, Wide­field Infrared Survey Explorer (WISE) or NASA InfraRed Telescope Facility (IRTF). We expect
that at least 10 out of 19 radar targets will produce datasets suitable for shape modeling.
