The following nongravitational three-apparition linkage has been computed
by the undersigned in partial collaboration with R. Kracht. See also MPEC
2004-X73 and 2010-H37. The adopted nongravitational parameters are A1 = +0.31,
A2 = -0.1892, and the 255 observations used are satisfied with mean residual
17".4.

The object passed 0.014 AU from the moon on 1999 June 12.09, 0.013 AU
from the earth on 1999 June 12.19 and 1.16 AU from Jupiter on 2008 June 24.
A moderately close approach to the earth occurs on 2010 May 29. The expected
magnitude is very uncertain, and the prediction below is undoubtedly too
bright. Nevertheless, the predicted position should be good to about 1',
and astrometry and photometry would be very desirable.
