Jupiter just went through Superior Conjunction (i.e., went behind the Sun as seen from the Earth), so it has been out of view for a while. Now that has returned, it is different — the South Equatorial Belt (SEB) is missing. The SEB has about 10 times the surface area of the Earth, so this is not a small change.

Agreed. Do you think the sun can absorb anything from Jupiter and that's the cause of the mysterious disappearance

It's not the first time the belt has disappeared - indeed, it happens every three to fifteen years. it last went missing in the early 1990s, and before that in 1973.
This time, though, the disappearance happened as the planet spent a three-month period behind the sun, so that on its emergence the transformation appears rather more sudden.
Over the next few months, we can expect to see a white spot appear which will gradually get stretched out by the planet's 350mph winds to form a new SEB.
Its rotation is the fastest of all solar system planets, rotating once on its axis every 10 hours. This means at the equator, Jupiter is moving at 22,000 mph, compared with 1,000 mph for the Earth.

No big deal. Just another cycle of Jupiter.
