Abstract:
Using the 2m telescope of the Bulgarian National Astronomical
Observatory at Rozhen, observations of 222 double or multiple stars
were carried out during three nights in 2011. This is the sixth series
of measurements of CCD frames of double and multiple stars obtained at
Rozhen. Also in 2011, using the 0.6m telescope of the Serbian
Astronomical Station on the mountain of Vidojevica, observations of
208 double or multiple stars were carried out during six nights. This
is the first series of measurements of CCD frames of double and
multiple stars obtained at this station. In this paper, we present the
results for the position angle and angular separation for 337 pairs
and residuals for 72 pairs with published orbital elements or linear
solutions. These observations have angular separations in the range
from 1.37'' to 172.81'', with a median angular separation of 7.66''.
We also present the recalculated linear solutions for four pairs and
one linear solution that has been calculated for the first time.
Description:
Using the 2m telescope of the Bulgarian National Astronomical
Observatory at Rozhen (NAOR), observations of 222 double or multiple
stars were carried out during three nights in 2011: one night on 2011
March 28/29 and two nights on 2011 October 27/28 and 28/29. This is
the sixth series of measurements of CCD frames of double and multiple
stars obtained at Rozhen. For each double or multiple star, 10 frames
were obtained: 5 in the Johnson B filter and 5 in the Johnson V
filter.
From June to the end of 2011, we carried out CCD observations of 208
visual double or multiple stars at the new Astronomical Station on the
mountain of Vidojevica (ASV). This station belongs to the Astronomical
Observatory of Belgrade. It is located in southern Serbia near the
town of Prokuplje. More details can be found at the observatory's Web
site (http://belissima.aob.rs/). Observations were carried out during
six nights: one night on June 18/19, August 19/20, and October 19/20,
and three nights on November 2-5.

Global Notes:
Note (G1): The separation and position angle are the average of data taken in
both the B and V filters when we use the VersArray 1300B and
Apogee Alta U42 CCD cameras. Note that the position angle has not been
corrected for precession, and it is thus based on the equinox for the epoch
of observation.
Note (G2): Between components of pairs determined by using package IRAF.
Note (G3): Apogee Alta, SBIG ST-10ME, VersArray 1300B.
