Saturn's polar vortex:Not exactly the "hot spot"indicated in the news

"This is a mosaic of 35 individual exposures made at the W.M. Keck I Observatory, Mauna Kea, Hawai'i, on Feb. 4, 2004 {I thought I'd seen something like this before --Ed.}. The prominent 'hot spot' at the bottom of the image is located at Saturn's south pole. The warming of the southern hemisphere was expected, as Saturn was just past southern summer solstice. The abrupt changes in temperature with latitude were not expected. The tropospheric temperature increases toward the pole abruptly near 70 degrees latitude from 88 to 89 Kelvin (-301 to -299 degrees Fahrenheit) and then to 91 Kelvin (-296 degrees Fahrenheit) right at the pole."
