Goldstone Radar Observations Planning: 2002 PZ39 at DSS-13
163373 2002 PZ39 2002 PZ39 was discovered on 2002 Aug 10 by LINEAR. This asteroid has an absolute magnitude of 18.9 that suggests a diameter of roughly 0.5 km, and lightcurves obtained in early 2020 by P. Pravec suggest a very slow rotation period of 149 hours (6.2 days). This asteroid will approach within 0.039 au on February 15. Observations are scheduled at Arecibo from Feb. 11-17 and will include reception at Green Bank, DSS-13, and elements of the VLBA. DSS-14 is not currently operational as a radar and will not be used for these observations. We are expecting moderately strong SNRs for this object at DSS-13. The SNRs at Arecibo will be strong enough for 7.5 m/pixel delay-Doppler imaging. Due to the very slow rotation period, the plan at DSS-13 is to integrate for and obtain one or two imaging snapshots per track. Integrations spanning two full hours will smear only a few degrees in rotation. At S-band, DSS-13 can receive only one channel: RCP. Fortunately Arecibo transmits LCP, so this should work fine. Green Bank is the primary receiver for Arecibo transmissions. At DSS-13 we will "eavesdrop." Pointing, Doppler, and time delay uncertainties for this object are very small. The Minor Planet Center has classified 2002 PZ39 as a "Potentially Hazardous Asteroid."
