Dear Friends,
Here's more info on the clouds seen on Uranus and another article just released
concerning a ring around Uranus and it's atmospheric fireworks.

Keck Telescope Images Of Uranus Reveal Ring, Atmospheric Fireworks
"Fourth of July fireworks" in Uranus' southern hemisphere (bright spot at left
of lower left image) indicate that vigorous convection is starting up, bringing
methane clouds to high altitudes for the first time in decades. The near
infrared Keck II images at 1.6 microns wavelength (top) show low altitude
clouds, in particular the polar collar and a nearby bright cloud. Observations
at 2.2 microns, however, reveal high-altitude features, including the cloud?s
bright core: presumably material rising up to high altitudes in Uranus'
atmosphere. (Credit: Heidi Hammel and Imke de Pater).by Robert Sanders

As summer draws to a close in the southern hemisphere of Uranus, storm clouds
are brewing in the upper atmosphere, northern hemisphere winds are gusting to
250 miles per hour, and the planet's rings are getting brighter every day.
This weather report comes from researchers using the Keck II 10-meter telescope
atop Mauna Kea volcano in Hawaii, where recent observations are proving that
Uranus is not the "boring and unchanging" planet people have assumed, according
to Imke de Pater, professor of astronomy at the University of California,
Berkeley.
The new images were obtained with the second-generation Near Infrared Camera
(NIRC2) using the adaptive optics system on the Keck II telescope.
