Broadband Photometry of Northern-Hemisphere Luminous Stars. VI. UBV Photometry for 62 case-Hamburg Stars
CCD-based UBV photometry for 62 intrinsically luminous stars (fifty-ninepreviously unobserved photometrically) drawn from volumes I, III, and Vof the Luminous Stars in the Northern Milky Way catalog is reported.These 62 stars include a number of bright giants and supergiants ofspectral types B, A, and F.

Measurements of double stars 1993.67 - 1998.13
624 Micrometer Measurements of 224 pairs with a 32.5 cm Cassegrain, 719Measurements of 310 double stars with a 360 mm Newtonian are given.Tables 1 to 4 are available in electronic form only at the CDS130.79.128.5 or via http://cdsweb.u-strasbg.fr/Abstract.html

UBV beta Database for Case-Hamburg Northern and Southern Luminous Stars
A database of photoelectric UBV beta photometry for stars listed in theCase-Hamburg northern and southern Milky Way luminous stars surveys hasbeen compiled from the original research literature. Consisting of over16,000 observations of some 7300 stars from over 500 sources, thisdatabase constitutes the most complete compilation of such photometryavailable for intrinsically luminous stars around the Galactic plane.Over 5000 stars listed in the Case-Hamburg surveys still lackfundamental photometric data.

A preliminary compilation of DS-programme star positions
A catalog is presented of the double-star-program (DS-program) starpositions, listing right ascensions for 930 DSs and declinations for1225 DSs of the program. The positions were compiled from the observedvalues obtained between 1980 and 1987 with the meridian circles of sixUSSR observatories (the Moscow, Kazan', Kiev, Khar'kov, Odessa, andTashkent Observatories) and the Belgrade Observatory. The measurementsand the treatment of the observational material were performed using therelative method, and the FK-4 system stars were used as reference stars.

The determination of the zero point of the wavelength scale on stellar spectrograms
A novel method for determining the zero point of the wavelength scale(lambda0) on low-spectral-resolution spectrograms obtainedwith an objective plasma is presented. The method was applied to a groupof 100 stars belonging to the B-G spectral classes. Near-UV spectrogramsof these stars were obtained by the Orion-2 space observatory.Equivalent widths were obtained for the resonance doublet of Mg II 2800A in the spectra of the stars studied.

Visual multiples. VIII - 1000 MK types
A total of 1000 new classifications are given for stars brighter than B= 8.0 mag in the Aitken double star catalog. The classificationssupplement 865 classifications obtained in 1981 and 1984. Among thenewly discovered stars are 12 new Ap stars, eight Lambda Bootis stars,one Ba II star, and 60 Am stars. A detailed list of the newclassifications is given.

Two-colour photometry and analysis of the eclipsing binary IM Aurigae
Photoelectric observations of the eclipsing binary IM Aur have beencarried out in B and V colors at the Ege University Observatory. Thelight curves were analyzed by means of Wood's model simulation programWINK and the Wilson-Devinney computer code. The system was found to be adetached binary with an undersized subgiant secondary nearly filling itsRoche limit. The absolute elements of the system are also deduced.

Spectral types for early-type stars observed by SKYLAB
MK spectral types are presented for 246 early-type stars observed withthe S-019 ultraviolet stellar astronomy experiment on Skylab. K-linetypes are also given where applicable, and various peculiar stars areidentified. The peculiar stars include five silicon stars, a shell star,a helium-rich star, a silicon-strontium star, a chromium-europium star,and two marginal metallic-line stars.
