R Aquarii is a nearby unique symbiotic star. The most notable observation is that R Aqr varies in brightness over the course of 387 days, going from an 11th magnitude star to a 6th magnitude star. Apart from this, it show peculiar polarization behaviour. Our earlier study on this source showed strong wavelength dependence of polarization and position angle which also showed strong time dependence. The variation in polarization in U-band was found to be much larger compared to that in longer wavelengths. To understand the long term polarization behaviour, we have been caring out polarimetry on this
source since 1995 from Mt Abu observatory, India. In the talk, general characteristics of R Aqr will be discussed along with the focus on the polarization behaviour of this peculiar star.
