Abstract
We present speckle interferometric measurements of binary stars performed during September and October of 2009 with the 2.1 m telescope of the Observatorio Astronómico Nacional at SPM (Mexico). We report here the results of 200 measurements of 196 pairs with a primary limiting magnitude of V = 12.3. The measured angular separations range from 0".115 to 5".26. Ninety seven pairs have separations less than 1". The mean error in separation is 0".03 and 1°.5 in position angle. The usual 180° ambiguity was corrected for a majority of position angles by comparison with observations performed by other observers.Similar Articles
