Jupiter has lost a band

Jupiter's appearance is usually dominated by two dark bands in its atmosphere – one in the northern hemisphere and one in the southern hemisphere.

But recent images taken by amateur astronomers show that the southern band – called the south equatorial belt – has disappeared.

The band was present at the end of 2009, right before Jupiter moved too close to the sun in the sky to be observed from Earth. When the planet emerged from the sun's glare again in early April, its south equatorial belt was nowhere to be seen...

Anyone who finds the band or has knowledge of where it could be is asked to contact NASA or the JPL by means of a comment at this post.
