The main-belt asteroid (16852) Nuredduna, was
observed between October and December 2017. The
synodic period is 6.3 ± 0.1 h.
Discovered in June 1995 at Steward Observatory, (16852)
Nuredduna was selected for observation from the “Lightcurve
Photometry Opportunities: Oct-Dec 2017” (Warner, 2017).
The observations of this main-belt asteroid lasted five nights
between October and December 2017. The observations were
carried out from F. Fuligni Observatory using a 0.35-m f/10 ACF
telescope and SBIG ST8-XE CCD camera with Bessel clear filter
and by Francesco Franceschini using a 9.25″ f/6.3 reflector
telescope equipped with Atik 314L+ CCD camera unfiltered. All
images were dark and flat-field calibrated with Maxim DL. The
lightcurve analysis has been performed with a differential
photometry technique extrapolating the best polynomial of
approximation of the observations, using the program MPO
Canopus (Warner, 2012). The resulting synodic period is found to
be P = 6.3 ± 0.1 h with an amplitude of A = 0.41 mag (Figure 1).
We would like to thank Fernando Pierri, Simone Nodari and
Samuele Piscitello for help in taking image frames and
maintenance of the ATA observatory instruments.
