Three known and twenty-two new variable stars of early spectral type
Photoelectric photometry is reported of three known and 22 newvariables, all brighter than V = 7.5 mag. The three known ones are: theellipsoidal variable 42 (V467) Per, the Beta Cep-type star HR 6684 =V2052 Oph, and the eclipsing variable HR 8854 = V649 Cas. The newvariable stars are listed. They include two Beta Cep candidates, oneeclipsing and three ellipsoidal variables, a 'mid-B' variable, anAlpha(2) CVn variable, and two Lambda Eri stars. The twelve remainingnew variables could not be classified because of insufficient data. TheLambda Eri variables found in the present investigation, together withsome examples from the literature, indicate that rotational modulationoccurs not only in Be, but also in normal B stars.

Digital speckle interferometry of 72 binary stars
Position angles and separations have successfully been measured for 72double stars with a digital speckle interferometer on the 6-m telescope.In both Theta and rho the internal measurement error is about 0.003 ofarc mins. The small residuals from published orbits indicate thatappreciable systematic effects are abent. In addition, 43 other starswere unresolved at the epochs specified.
