2012 QC8 Goldstone Radar Observations Planning
2012 QC8 was discovered by the Siding Spring Survey on August 19, 2012. The orbit of this asteroid is unusual, with a Tisserand parameter of 2.799, and it resembles a Jupiter-family comet. 2012 QC8 will approach Earth within 23 lunar distances (LD) on Sep 14, 2012, its closest approach for the foreseeable future. Given its comet-like orbit, and based on our previous experience with the similar objects (17 NEAs with Tisserand <3 have been observed with radar so far), we assume that its optical albedo is low, on the order of ~5% or less. When combined with its absolute magnitude of 18.0, we obtain ~1.5 km diameter. Due to the short notice, Goldstone has a single track scheduled on Sep 23 when 2012 QC8 is already >0.1 AU away. 2012 QC8 will be a weak target, and it is possible that we will have trouble detecting it unless it proves to be a large object with a slow rotation period. 2012 QC8 has remained at high southern declinations since its discovery, and it does not cross Arecibo's declination window until Sep 30 when it is already at 0.2 AU. However, even at that distance it will be a stronger target for Arecibo (SNRs~6/run) than for our scheduled track at Goldstone (SNRs~2/run). We may request a track or two at Arecibo if this turns out to be an interesting object. 2012 QC8 brightens below 15 mag in mid-September, when it is circumpolar for the southern hemisphere observers. Unfortunately, it is also very close to the Sun and it becomes a daytime object after Sep 16. Lightcurves, spectroscopy and astrometry are highly desirable prior to the radar observing campaign, but to the best of our knowledge, nobody has reported any.
