(Sorry, its declination makes for poor viewing for southern observers. It will remain faint throughout 2010 before slowly brightening to its normal luster by mid-2011. (SkyAndTelescope.com)
NASA falling short of asteroid-detection goals Aug 14, 2009
The Arecibo Observatory telescope continues to play a unique role in characterization of NEOs, providing unmatched precision and accuracy in orbit determination and insight into size, shape, surface structure, multiplicity, and other physical properties for objects within its declination coverage and detection range. The United States is the only country that currently has an operating survey/detection program for discovering near-Earth objects; Canada and Germany are both building spacecraft... (CNN)
