GOLDSTONE RADAR IMAGES OF 2007 PA8 18.75 meters x 0.03 Hz
(214869) 2007 PA8 was discovered by LINEAR on August 9, 2007. Nothing is known about the physical properties of this object except its absolute magnitude of 16.2, which suggests a diameter within a factor of two of about 1.8 km. 2007 PA8 will approach within 0.043 AU (17 lunar distances) on November 5, 2012, when it could be a very strong radar target at Goldstone. We are planning an extensive campaign of Goldstone radar observations and hope to use the chirp system to image this object. With a Tisserand parameter of 2.944, the orbit of this asteroid resembles that of a Jupiter-family comet. Update: The preliminary radar data from Goldstone suggest that the object is 1.5-2 km in diameter and a very slow (period of days) rotator. Due to the strong SNRs and size of the object, we expect that radar imaging will place hundreds or possibly thousands of pixels on this object at resolutions of 0.125 or finer. Fourteen tracks are scheduled at Goldstone between October 28-November 13, providing an outstanding opportunity to study the physical properties of this object. View periods for 2007 PA8 also overlap those scheduled for asteroid 1998 ST49 on October 16-19, and we plan to devote some of the time on those dates to 2007 PA8 as well. The closest approach occurs at declinations too far south for Arecibo to track. 2007 PA8 brightens below 15th magnitude at the end of September and it reaches a peak brightness at magnitude 11 just before the closest approach. It will be an excellent target for lightcurves and spectroscopy and it will even be visible in small telescopes (8" and larger) for experienced observers. 2007 PA8 has been classified as a "Potentially Hazardous Asteroid" (PHA) by the IAU's Minor Planet Center.
