The Pul-3 catalogue of 58483 stars in the Tycho-2 system
A catalogue of positions and proper motions of 58483 stars (Pul-3) hasbeen constructed at the Pulkovo observatory. The Pul-3 is based on theresults of measurements of photographic plates with galaxies (Deutsch'splan). All plates were taken using the Pulkovo Normal Astrograph (thefirst epoch is in the 1950s and the second epoch is in the 1970s).The Pul-3 catalogue contains stars of mainly 12 to 16.5 mag in 146fields with galaxies in the declination zone from -5o to+85o. The Tycho-2 has been used as a reference catalogue.The mean epoch of the Pul-3 is 1963.25. The internal positional accuracyof the Pul-3 catalogue at the mean epoch of observations is ±80mas. The accuracy of the proper motions is mostly within ±3mas/yr to ±12 mas/yr. Comparisons of the Pul-3 with Tycho-2 andARIHIP have been done at the mean epoch of the Pul-3. The Pul-3 externalpositional accuracy relative to Tycho-2 is ±150 mas.The catalogue is only available in electronic form at the CDS viaanonymous ftp to cdsarc.u-strasbg.fr (130.79.128.5) or viahttp://cdsweb.u-strasbg.fr/cgi-bin/qcat?J/A+A/418/357

Identification of X-ray sources <1° from Seyfert galaxies.
Excess numbers of X-ray sources around bright Seyfert galaxies have beendemonstrated with significances of association up to 7.4-sigma (Radecke,preceding paper). The optical identification of these sources is shownhere to be predominantly blue stellar objects (BSO's) of which some arealready catalogued as quasars. Excluding the two brightest Seyferts, asubset of 24 with apparent magnitudes between8.04<=B_T_^o,i^<=12.90mag. show a minimum excess of >46 brightX-ray sources. These excess X-ray sources are generally distributedbetween 10'

GPM1 - a catalog of absolute proper motions of stars with respect to galaxies
The description of the first version of the General Compiled Catalogueof Absolute Proper Motions (GPM1) for a sample of HIPPARCOS stars,derived with respect to galaxies within the plan called Catalogue ofFaint Stars (KSZ, Deutch 1952), is presented. The principal aim of theGPM1 construction was to provide absolute proper motions of stars todetermine the rotation of the HIPPARCOS system. The GPM1 cataloguecontains 977 HIPPARCOS Input Catalogue stars with V magnitudes $5^m -11^m in 180 fields north of -25 degrees of declination. The accuracy ofthe proper motions is 8 mas/yr (milliarcseconds per year). Comparison ofproper motions of GPM1 with those of the PPM and ACRS was performed andanalyzed with respect to systematic errors caused by spurious rotationof the FK5 system. The standard errors show that the rotation may bedetermined with an accuracy better than 1 mas/yr. Catalog is onlyavailable in electronic form at the CDS via anonymous ftpcdsarc.u-strasbg.fr or ftp 130.79.128.5.

Photometric survey near the main Galactic meridian: 2.1. Finding charts and photoelectric U,B,V,R stellar magnitudes in 25 fields
Finding charts and photoelectric U,B,V,R magnitudes of stars in 25fields in the Main Galactic Meridian (programme MEGA) are presented.This part of the photometric survey includes fields near the NorthGalactic pole and fields at southern Galactic latitudes. Together withthe finding charts of 2.5(deg) x2.5(deg) the equatorial coordinates ofthe stars are given for epoch and equinox 1950.

Classification of a sample of field stars in the direction of the North Galactic Pole by multicolour Vilnius photometry
An automated classification in spectral types, luminosities andmetallicities using the photometric observations in the Vilnius systemof a sample of 78 field stars in the direction of the North GalacticPole has been achieved, using a new software. For comparison, thespectral classification has been done by the discrete two-colour andtwo-Q methods developed by Vilnius astronomers, and the results arefound to be in good agreement. The ages of the field stars are estimatedfrom isochrones in the HR diagram.

Photoelectric Photometry of Stars Near the North Galactic Pole in the Vilnius System - Part One - Kiev Area 112
Seven-color photoelectric photometry in the Vilnius system is presentedfor 78 stars in Kiev Area 112 near the north galactic pole. The surveyarea of 1°20arcmin diameter is centered at α1950 =13h40m.2, δ1950 =+36°27arcmin. It represents one of the 21 northern areas along themain meridional section of the Galaxy for which absolute proper motionsrelative to galaxies are measured in Kiev. The photoelectric catalogincludes all the stars of the area down to V = 12.8.
