ORLOV, V. G. e VOITSEKHOVICH, V. V.. Speckle interferometry at the Observatorio Astronómico Nacional. VI. Rev. mex. astron. astrofis [online]. 2015, vol.51, n.1, pp.65-72. ISSN 0185-1101.
We present speckle interferometric measurements of double stars performed during August of 2010 with the 1.5 m telescope and during May of 2010 with the 2.1 m telescope of the Observatorio Astronómico Nacional at SPM (México). We report here the results of 331 measurements of 321 systems with a primary limiting magnitude of V = 12.9. The measured angular separations range from 0".13 to 7".39. Two hundred and sixty-nine pairs have separations less than 1". The mean error in separation is 0".032 and 2° in position angle. The usual 180° ambiguity was corrected for the majority of position angles by comparison with observations performed by other observers.
