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. Tables 1 and 2 are only available in electronic form at theCDS via anonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/Abstract.html

The emission-line stars in NGC 663
The young galactic cluster NGC 663 has been observed on a series ofobjective-prism plates obtained during the period from 1946 to 1975, inorder to establish the percentage of Be stars in this cluster and todetermine the frequency of 27 H-alpha emission-line variables. Theresults indicate that H-alpha emission is firmly established in 18 starsreported in more than one independent survey, that the Be stars areconfined to spectral types B5 and earlier, and that at least one-thirdof the early B-type cluster members have exhibited Be characteristics atone time or another. It is also found that large-amplitude variations inthe strength of the H-alpha emission occurred during the three-decadeinterval in one-third of the Be stars on a time scale of several years.A color-magnitude diagram is plotted for the confirmed emission-line inNGC 663.

Noncircular motions in the Perseus spiral arm
An examination of the motions of the optical spiral tracers in thePerseus arm reveals a clear kinematic separation between the inner andouter sides of the arm. Those objects on the inner or near side have amean velocity residual of -10.7 km/s, while those on the outer or farside have a mean positive residual of +7.0 km/s. These velocityresiduals are interpreted in terms of the linear density-wave theory asstreaming motions between the sides of the arm. Plausible solutions forthe amplitudes of the noncircular motions yielded 10 to 20 km/s and 7 to15 km/s for the radial and tangential components, respectively. Theseresults are about twice the amplitudes suggested by the theory.
