We present mean proper motions and membership probabilities of individualstars for optically visible open clusters, which have been determined usingdata from the UCAC5 catalog. This follows our previous studies with the UCAC2and UCAC4 catalogs, but now using improved proper motions in the GAIA referenceframe. In the present study results were obtained for a sample of 1108 openclusters. For five clusters, this is the first determination of mean propermotion, and for the whole sample, we present results with a much larger numberof identified astrometric member stars than on previous studies. It is the lastupdate of our Open cluster Catalog based on proper motion data only. Futureupdates will count on astrometric, photometric and spectroscopic GAIA data asinput for analyses.
