From May 6-8, 2006 the Arecibo radio telescope will be obtaining data from asteroid 99942 Apophis. The next good observation window for Arecibo may be in January 2013.
From A/CC's minor object news:
"Arecibo is requesting photometry -- 'physical observations (lightcurves, colors, etc.)' -- to help prepare for radar observation on 6-8 May 2006. About astrometry, NEODyS notes that 'Only very accurate observations are useful' for risk analysis."
