Thanks for pointing out that paper, Paolo. It was interesting. I noted the penultimate paragraph:

QUOTE
From ground-based observations (132524) 2002 JF56 is classified as an S-type asteroid. The axis-ratio determined shows that during the time of observation no large changes of the asteroid’s cross-section took place. The estimated effective diameter is in agreement with that obtained by the New Horizons mission (approximately 2.5 km) observations (http://pluto.jhuapl.edu/gallery/missionPho...s/asteroid.html). A determination of the rotational period may be possible by combining set of photometric data from different observers.

Speaking of which, anybody has a copy of the poster "The New Horizons Distant Flyby of Asteroid 2002 JF56" by Catherine Olkin et al presented at last year's DPS meeting? I have tried to ask the author but has not replied to me yet
