2012 OQ Goldstone Radar Observations Planning
2012 OQ was discovered by the La Sagra Sky Survey in Spain on July 16, 2012. Not much is known about this object except that its absolute magnitude of 21.8 suggests a diameter of ~0.14 km (within a factor of two). 2012 OQ belongs to the Apollo class of asteroids and it has been classified as a "Potentially Hazardous Asteroid" by the Minor Planet Center. This object approached within 7.7 lunar distances on July 24 and it's now moving away from Earth rapidly. Its view periods overlap with times previously scheduled for 2002 AM31 on July 27 and 28. We plan to devote some of our time to 2012 OQ on one or possibly both of those dates. We are expecting 2012 OQ to be a relatively weak CW target.

Goldstone SNRs assume Ptx = 450 kW. Only one klystron is functional, so
the SNRs may be weaker.

CW setup:

This object has large Doppler uncertainties, and we may see a Doppler correction
of up to several hundred Hz, so we're going to start with a wider bandwidth than usual:

RCV polarization LCP & RCP
Frequency hops: 2
Dwells: 20
Bandwidth: 8000 Hz
Sampling interval: 1250 x 0.1 usec
VME FFT for PSD files: 4096 for 1.95-Hz resolution
Once we improve the solution, we'll switch to:
