The successful prediction of lensing events is a new and exciting enterprisethat provides opportunities to discover and study planetary systems. Thecompanion paper investigates the underlying theory. This paper is devoted tooutlining the components of observing programs that can discover planetsorbiting stars predicted to make a close approach to a background star. If thetime and distance of closest approach can be well predicted, then the systemcan be targeted for individual study. In most cases, however, the predictionswill be imprecise, yielding only a set of probable paths of approach and eventtimes. We must monitor an ensemble of such systems to ensure discovery, astrategy possible with observing programs similar to a number of currentsurveys, including PTF and Pan-STARRS; nova searches, including those conductedby amateurs; ongoing lensing programs such as MOA and OGLE; as well as MEarth,Kepler and other transit studies. If well designed, the monitoring programswill be guaranteed to either discover planets in orbits with semi-major axessmaller than about two Einstein radii, or else to rule out their presence.Planets on wider orbits may not all be discovered, but if they are common, willbe found among the events generated by ensembles of potential lenses. Weconsider the implications for VB 10, the first star to make a predictedapproach to a background star that is close enough to allow planets to bediscovered. VB 10 is not an ideal case, but it is well worth studying. A moreconcise summary of this work, and information for observers can be found athttps://www.cfa.harvard.edu/~jmatthews/vb10.html.
