Absolute proper motions of open clusters. I. Observational data
Mean proper motions and parallaxes of 205 open clusters were determinedfrom their member stars found in the Hipparcos Catalogue. 360 clusterswere searched for possible members, excluding nearby clusters withdistances D < 200 pc. Members were selected using ground basedinformation (photometry, radial velocity, proper motion, distance fromthe cluster centre) and information provided by Hipparcos (propermotion, parallax). Altogether 630 certain and 100 possible members werefound. A comparison of the Hipparcos parallaxes with photometricdistances of open clusters shows good agreement. The Hipparcos dataconfirm or reject the membership of several Cepheids in the studiedclusters.

| Catalogue of blue stragglers in open clusters.
An extensive survey of blue straggler candidates in galactic openclusters of both hemispheres is presented. The blue stragglers wereselected considering their positions in the cluster colour-magnitudediagrams.They were categorized according to the accuracy of thephotometric measurements and membership probabilities. An amount of 959blue straggler candidates in 390 open clusters of all ages wereidentified and classified. A set of basic data is given for everycluster and blue straggler. The information is arranged in the form of acatalogue. Blue stragglers are found in clusters of all ages. Thepercentage of clusters with blue stragglers generally grows with age andrichness of the clusters. The mean ratio of the number of bluestragglers to the number of cluster main sequence stars is approximatelyconstant up to a cluster age of about 10^8.6^ yr and rises for olderclusters. In general, the blue stragglers show a remarkable degree ofcentral concentration.
| Photometric study of the Southern open clusters NGC 5316 and NGC 6214
Based on UBV photoelectric photometry, the individual reddenings ofcluster stars in NGC 5316 and NGC 6124 were derived, and a fitting to anevolved sequence was performed on the reddening-free colors andmagnitudes of cluster members. For NGC 5316, an average distance modulusof 10.34 + or - 0.07, an E(B-V) value of 0.34 + or - 0.04 s.d., and anage of about 1.2 x 10 to the 8th yr were found. For NGC 6124, an E(B-V)value of 0.80 + or - 0.06 s.d., an average distance modulus of 8.75 + or- 0.04, and an age of about 1.0 x 10 to the 8th yr are determined. Thepresent color excesses and distance moduli are, in general, greater thanprevious values.
