2009 UN3 Goldstone Radar Observations Planning
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.
