Changing brightness of R Aquarii

Already in 1810 astronomers discovered that the brightness of the star R Aquarii periodically changes and it has subsequently been found to vary with a period of approximately a year. During these cycles, R Aquarii has been seen to fade into obscurity and then become so bright as to almost be visible to the naked eye. This animation is an artistic representation of this change in brightness.
