Abstract
We present speckle interferometric measurements of binary stars performed during September, October and November of 2009 with the 1.5-m telescope of the Observatorio Astronómico Nacional at SPM (Mexico). We report here the results of 645 measurements of 504 pairs of stars with a primary limiting magnitude of V=12.3. The measured angular separations range from 0arcsec.144 to 5arcsec.17. 396 pairs have separations of less than 1''. The mean error in separation is 0arcsec.033 and in position angle, 0arcdeg.9. The usual 180arcdeg ambiguity was corrected for the majority of position angles by comparison with observations performed by other observers.Similar Articles
