Abstract:
We present speckle interferometric measurements of binary stars
performed during August of 2010 with the 1.5m telescope and during
November of 2010 with the 2.1m telescope of the Observatorio
Astronomico Nacional at SPM (Mexico). We report here the results of
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 in
separation is 0.03" and 1.5° in position angle. Some of the
position angles were determined with the usual 180° ambiguity.
Description:
Data were recorded during the two observation campaigns carried out in
August and November 2010. In August observations of 105 stars were
performed at the OAN-SPM 1.5m telescope.
For three nights in November 2010 we observed 120 stars with the 2.1m
telescope of OANSPM.
