Jupiter is in the midst of a North Temperate Belt revival. I photographed at least three new white spots within the canonical NTB latitudes on March 29 UT 2007. The arrow in the image below shots the large complex composed of two spots, as well as two of the moons of Jupiter and their shadows on the disk of the planet. The NTB spots have now increased in number and are associated with dark blue-gray cloud within the NTB (see the April 5 images). Over the next few weeks, these features in the NTB will increase in complexity, filling the entire NTB with numerous white and dark spots, but decrease in visibility - the white spots will become less intense. Eventually, the NTB will be dark again. The white NTB spots are also bright in methane band images indicating that these features extend high into the Jovian atmosphere. Such outbreaks have not been photographed in detail, since 1990.

The false-colour image shows the composite of near-UV, near-IR and methane band images shows in red, green and blue channels. Clearly, the NTB spots are bright at all three wavelengths. The bluish oval in the southern hemisphere (at top) is oval BA.
