2009 UN3 Goldstone Radar Observations Planning


Background


This asteroid was discovered on Oct 19, 2009 by the Siding Spring Survey in
Australia.  2009 UN3 has an absolute magnitude of 17.7, suggesting
a diameter within a factor of two of 920 meters, and it has a rotation
period of 8.4 h.  Its lightcurve amplitude of 0.35 mag suggests a 
moderately elongated shape.   2009 UN3 will approach
within 0.037 AU (14.3 lunar distances) on February 9, 2010, when
it will be a strong radar target.  Using recent experience as a guide,
there is a 1/6 chance that it's a binary system.

2009 UN3 is currently a southern sky object and its declination 
remains south of -30 deg until after Feb. 8.

We have three days scheduled for this object at Goldstone (Feb. 8, 9, and 11);
the one track at Arecibo, on Feb. 10, has been cancelled due to maintenance.

2009 UN3 has been classified as a "Potentially Hazardous Asteroid" by the 
Minor Planet Center.
