Speckle Interferometry at the Observatorio Astronómico Nacional. II
We present speckle interferometric measurements of binary stars madeduring June of 2009 with the 1.5 m telescope of the ObservatorioAstronómico Nacional at SPM (Mexico). The data contain 189position angle and separation measures of 144 systems. The measuredangular separations range from 0arcsec.16 to 3arcsec.64. The maximummagnitude of the brighter component is 10.96. The mean error inseparation is 0arcsec.02 and in the position angles 1.5°. Some ofthe position angles were determined with the usual 180° ambiguity.

Two-colour photometry for 9473 components of close Hipparcos double and multiple stars
Using observations obtained with the Tycho instrument of the ESAHipparcos satellite, a two-colour photometry is produced for componentsof more than 7 000 Hipparcos double and multiple stars with angularseparations 0.1 to 2.5 arcsec. We publish 9473 components of 5173systems with separations above 0.3 arcsec. The majority of them did nothave Tycho photometry in the Hipparcos catalogue. The magnitudes arederived in the Tycho B_T and V_T passbands, similar to the Johnsonpassbands. Photometrically resolved components of the binaries withstatistically significant trigonometric parallaxes can be put on an HRdiagram, the majority of them for the first time. Based on observationsmade with the ESA Hipparcos satellite.
