Description:
The results of speckle interferometric observations of 194 binary
stars performed at the BTA 6m telescope in 2002-2006 are presented in
this paper. For speckle observations we used filters with central
wavelengths from 545 to 800nm and speckle camera with the fast CCD
coupled with a tree-chamber intensifier. The most part of the observed
systems (80 stars) - pairs, which binarity was discovered by Hipparcos
satellite fo the first time. And the other stars are visual binaries
and interferometric binary systems which orbital periods estimates
from several to ten of the year. The pairs with slow orbital motion
are included to the observation list, also. They are used for position
parameters calibrations.
