The precise radial velocity survey at Keck Observatory began over 20 yearsago. Its survey of thousands of stars now has the time baseline to be sensitiveto planets with decade-long orbits, including Jupiter analogs. I presentseveral newly-finished orbital solutions for long-period giant planets.Although hot Jupiters are generally "lonely" (i.e. they are not part ofmultiplanet systems), those that are not appear to often have giant companionsat 5 AU or beyond. I present two of the highest period- ratios among planets ina two-planet system, and some of the longest orbital periods ever measured forexoplanets. In many cases, combining Keck radial velocities from those fromother long-term surveys at Lick Observatory, McDonald Observatory, HARPS, and,of course, OHP spectrographs, produces superior orbital fits, constraining bothperiod and eccentricity better than could be possible with any single setalone. Stellar magnetic activity cycles can masquerade as long-period planets.In most cases this effect is very small, but a loud minority of stars,including, apparently, HD 154345, show very strong RV-activity correlations.
