Abstract:
We present speckle interferometric measurements of binary stars
performed during September and October of 2009 with the 2.1m telescope
of the Observatorio Astronomico 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
100. 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.
Description:
The observations were performed at the 2.1-m telescope of the
Observatorio Astronomico Nacional which is located at the San Pedro
Martir (Mexico).
