Here are approximate elements:

1 39025U 12071A   14159.06527264  .00017042  00000-0  10000-3 0    03
2 39025  43.5039 182.1043 0010000 359.8704   0.2170 15.77261939    01

RAAN probably is accurate to within a few tenths of a degree.

Mean motion is somewhat uncertain. I suggest prediction time uncertainty allowance of 2 min. per 24 h from epoch.
