Two wide stripes—known as the equatorial belts—normally circle the huge planet, products of the fast-moving jet streams that roar through Jupiter's atmosphere.
But in May this year the southern equatorial belt dissaperead leaving what is usually a dark redish brown belt to now a pale white belt. This also makes the Giant Red Spot appear duller.
This doesnt concern most astronamers becuase a similiar event happend in 1990. But the southern equatorial belt didnt completly dissapeared, only became smaller.
The southern equatorial belt is expected to make its return with in 1 to 3 years returning Jupiter back to its 'normal' self
