2001 CQ36 Goldstone Radar Observations Planning
2001 CQ36 was discovered by the Lincoln Laboratory ETS (LINEAR) in New Mexico on February 13, 2001. This ~70-meter-diameter (Mueller et al. 2012) asteroid has been flagged on the NASA Near-Earth Object Human Space Flight Accessible Targets Study (NHATS) website (http://neo.jpl.nasa.gov/nhats/) as a candidate for human exploration. 2001 CQ36 will approach within 0.0258 AU (~10 lunar distances) on May 30, 2012. This asteroid will be a weak radar target at Goldstone and Arecibo. The asteroid will approach from the south, so it will be detectable at Goldstone before it enters the beam at Arecibo. 2001 CQ36 is observable from Arecibo beginning on June 11 when the distance has receded to about 0.047 AU. Photometry reported by Hergenrother and Whiteley (2011) did not uncover the rotation period of this object, possibly due to a long rotation period, a very short rotation period, and/or a very small lightcurve amplitude. Mueller et al. estimate that 2001 CQ36 has an unusually bright optical albedo of about 0.4. This will likely be a CW and ranging target target at Goldstone and we expect to see a narrow bandwidth if it turns out to be a slow rotator. Even though the SNRs at Goldstone are weak, this is a very high-priority object due to its implications for future human space missions. For optical observers, 2001 CQ36 will become a daytime object by the end of May. It will become visible again in August, but it will be very, very faint (~25 mag).
