Speckle Interferometry at the Observatorio Astronómico Nacional. III
We present speckle interferometric measurements of binary starsperformed during August of 2010 with the 1.5 m telescope and duringNovember of 2010 with the 2.1 m telescope of the ObservatorioAstronómico Nacional at SPM (Mexico). We report here the resultsof 238 measurements of 225 pairs with a primary limiting magnitude of V= 12.2; 211 of them have separations less than 1''. The mean error inseparation is 0.03 arcsec 1.5° in position angle. Some of theposition angles were determined with the usual 180° ambiguity.
