Revision to MPEC 2010-N10
On June 17 and 18, 2020, T. Lister (K93) reported recovery of Near-Earth
Object 2002 BF25. D. Farnocchia (JPL) suggested the presence of Yarkovsky
non-gravitational forces affecting the orbit. MPC orbit integration detected
the presence of Yarkovsky effect and derived the parameter
A2=162.0602e-15 +/- 6.3594e-05 au/d^2.
