Anisotropy in the aberration constant due to galactic rotation

It is shown that in the near future it will be possible to detect the dependence of the aberration constant on the direction to a star caused by our secular rotation. The corresponding corrections to the visible stellar positions will increase the accuracy in determining the Earth's rotation parameters by astro-optical means.
