Follow-up of 164P/Christensen
(200 words excerpt, click title or image to see full post)

On 2010, Oct 28.47, we were able to secure some additional follow-up about the faint returning comet 164P/Cristensen. The images were obtained through the Faulkes Telescope South (Siding Spring, Australia), a 2.0-m f/10.0 Ritchey-Chretien + CCD.At the time of our observation the comet was about 70 deg above the horizon, in a moonless sky. Under good seeing conditions (FWHM of nearby field stars about 1 arcsec) we stacked several R filtered exposures, 60-sec each, and found the comet moving at the expected postion: 164P/Christensen was a starlike object, at about magnitude R~ 20.Please click here for a bigger version.Its measured astrometry was in good agreement with our previous recovery data batch of 2010, Oct 7 and 11 (see our previous post here).We kindly acknowledges the Faulkes Telescope Project for the telescope time we used.by N. Howes, G. Sostero and E. Guido
