> From 236 observations 1995-2011, mean residual 0".88.
Nongravitational parameters A1 = +0.50 ± 0.01, A2 = -0.0474 ± 0.0000.
Orbit was improved except all 2006 observations.
The delta-T correction for the prediction in NK 1357 (= MPC 62881,
HICQ 2011/2012) was +0.034 day with the RunOff value -71" for R. A.
and -18" for Delc.. See the previous orbits in NK 673, NK 807, NK 936
and NK 1357.
