Abstract (from CDS):

The asteroid (132524) 2002 JF56 was the distant fly-by target of the New Horizons spacecraft on June 13, 2006. To further enhance our knowledge of this asteroid and facilitate the cross-calibration of the spacecraft instruments, ground based observations of the asteroid were performed in May 2006 at ESO VLT. Photometry and spectroscopy of (132524) 2002 JF56 were performed: a set of R filter broadband images and reflectance spectra were taken with FORS2 of the ESO VLT for a total of three nights (May 25, 30 and 31, 2006). Each observational cycle spans a time interval of about one hour per night. The observations were performed about two weeks before the fly-by, when the asteroid was at a heliocentric distance of 2.5AU. The reflectance spectra of 2002 JF56 resemble those of S-type asteroids. From the photometry of the asteroid, an effective diameter of about 2.3km is estimated and a lower limit for the axis-ratio of (1.19±0.02) is determined.
