Radar Detection of 2012 QG42
- Greetings Everyone,
I want to inform you that we successfully detecte radar echoes from 2012 QG42
at Goldstone on September 13. The astrometry that many of you provided was
invaluable so thank you very much for your help!
We spent most of our time during the track improving the orbit by estimating
Doppler and ranging corrections to the ephemerides. The radar data are
consistent with a slow rotation period as inferred from the lightcurves
reported by Brian Warner.
We have one more track scheduled at Goldstone on Sep. 15 and four tracks at
Arecibo on Sep. 14-17.
