Proper motions of open clusters based on the TYCHO2 Catalogue. II. Clusters farther than 1 kpc
We determined the mean absolute proper motion of 94 open clusterssituated farther than 1 kpc from the Sun. The results are derived fromthe stellar proper motion data given in the Tycho2 Catalogue. The meanproper motion of the clusters and membership probability of individualstars were obtained from the proper motion data by applying thestatistical method proposed by Sanders (\cite{Sanders1971}). Themeasurements made use of a large number of stars, usually several tens,for each cluster. The total number of stars investigated in the fieldsof the clusters is 4864 of which 2021 were considered members. For 55clusters, this is the first determination of the proper motion. Based onobservations of the ESA Hipparcos satellite.

Globular clusters and the Mira period-luminosity relation
A globular cluster distance scale based on Hipparcos parallaxes ofsubdwarfs has been used to derive estimates of MK for clusterMiras, including one in the Small Magellanic Cloud (SMC) globularcluster NGC 121. These lead to a zero-point of the Mira infraredperiod-luminosity (PL) relation, PL(K), in good agreement with thatderived from Hipparcos parallaxes of nearby field Miras. The mean ofthese two estimates together with data on LMC Miras yields a LargeMagellanic Cloud (LMC) distance modulus of 18.60+/-0.10 in evidentagreement with a metallicity-corrected Cepheid modulus (18.59+/-~0.10).The use of luminous asymptotic giant branch (AGB) stars as extragalacticpopulation indicators is also discussed.
