However, it is recorded that the size of the Red Giant Spot shrinking rapidly for quite some time and has been slowing down for recent years.
In 1979, Voyager 1 and 2 spacecraft revealed that the entire system of Red Giant Spot rotates counter-clockwise and takes about six days to complete one rotation.
