“…Finally, during four nights in February 2003, Gandolfi et al (2009) observed Gretia obtaining very high quality lightcurves with each of the extrema having a different level and an amplitude 0.66 ± 0.02 mag, from which the period was found to be 5.780 ± 0.001 h. All of the published lightcurve data, apart from the last set, was used in our modelling of this object. We added seven apparitions (1997, 1999, 2002, 2005, 2006, 2007/2008, and 2009) to the existing set of observations.…”

We analyze photometric observations of the three main-belt asteroids 350 Ornamenta, 771 Libera, and 984 Gretia, conducted over a twelve-year interval. Our data and those of other authors allow us to determine pole and shape models using the lightcurve inversion technique. In all three cases, a single pole solution was obtained without any significant mirror solution:This analysis and the development of asteroid models increase the set of asteroids with known spin and shape parameters, which consists of only around 100 objects.

Hungaria region locates the inner edge of asteroidal main belt with the high orbital inclination and is surrounded by several resonances, in which more small asteroids (size less than 11 km) reside. We estimate the spin states for eight fast (rotation period ) rotators in this region based on the dense photometric data and discover that seven of them are in the retrograde spin state. By the analysis on the distributions of spin characteristics, 35 out of 59 Hungaria region members exhibit a tendency—their obliquities distribute in the range larger than , and especially, most of them clustering significantly in the interval of . Meanwhile, it is also noted that the Hungaria region asteroids with the fast spin (rotation period ) show more significant clustering characteristic.
