An analysis of monitoring observations for the pulsar PSR B0655+64, which is located in a
binary system, at 111 MHz during 2002–2015 are presented. The Keplerian parameters of the pulsar
have been refived: the longitude of periastron ω = 276 ◦ .5785 ± 0 ◦ .0005 and the orbital semi-major axis
is a p sin i = 4.124976 ± 0.000003 s. The parameters of the perturbed motion have been determined:
the motion of periastron ω  ̇ = 0 ◦ .315 ± 0 ◦ .005/ year, and the derivative of the period of the binary system
P  ̇ = (−1.66 ± 0.11) × 10 −14 s/s = (−0.524 ± 0.038) μs/year. The estimated time scale for the decay of
the PSR 0655+64 system is (1.7 ± 0.1) × 10 11 yrs.
