Proposal Title: Urgent Proposal for Radar Imaging of Asteroid 2000 EH26
ABSTRACT:
This recently discovered asteroid, classied as potentially hazardous by the IAU/Minor Planet Center, approaches
to within 0.041 AU of Earth during the requested tracks. Its eective diameter is probably within a factor of two of
140 meters, a size range that is virtually unexplored by previous asteroid radar observations. The echo strength
should support decameter-resolution imaging and, if the orientational coverage is adequate, reconstruction of a
three-dimensional shape model.
