AB V1432 Aquilae is the only known eclipsing asynchronous polar. In this respect it is unique and therefore meritsour attention. We report the results of a 15-year campaign by the globally distributed Center for BackyardAstrophysics to observe V1432 Aql and investigate its return to synchronism. Originally knocked out ofsynchrony by a nova explosion before observing records began, the magnetic white dwarf in V1432 Aql iscurrently rotating slower than the orbital period but is gradually catching up. The fortuitously high inclination ofthe binary orbit affords us the bonus of eclipses providing a regular clock against which these temporal changescan be assessed. At the present rate, synchronism should be achieved around 2100. The continually changingtrajectory of the accretion stream as it follows the magnetic field lines of the rotating white dwarf produces acomplex pattern of light emission which we have measured and documented, providing comprehensiveobservational evidence against which physical models of the system can be tested.
