  In 1965 Paul D. Jose published his discovery that both the motion of the Sun
about the center of mass of the solar system and periods comprised of eight
Hale magnetic sunspot cycles with a mean period of ~22.37 years have a matching
periodicity of ~179 years. We have investigated the implied link between solar
barycentric torque cycles and sunspot cycles and have found that the unsigned
solar torque values from 1610 to 2057 are consistently phase and magnitude
coherent in ~179 year Jose Cycles. We are able to show that there is also a
surprisingly high degree of sunspot cycle phase coherence for times of minima
in addition to magnitude correlation of peaks between the nine Schwabe sunspot
cycles of 1878.8 to 1976.1 (SC12 through SC20) and those of 1699 to 1798.3
(SC[-5] through SC4). We further show that the remaining seven Schwabe cycles
in each ~179 year cycle are non-coherent. In addition we have analyzed the
empirical solar motion triggers of both sunspot cycle phase coherence and phase
disruption, from which we conclude that sunspot cycles SC28 through SC35 (2057
to 2143) will be phase coherent at times of minima and amplitude correlated at
maxima with SC12 through SC19 (1878.8-1964.8). The resulting predicted start
times +/- 0.9 year, 1 sigma, of future sunspot cycles SC28 to SC36 are
tabulated.
