Since we're discussing Subaru:
"Jupiter's Atmosphere Heats up under Solar Wind"
Similar to Earth, the interaction of the solar wind and Jupter's magnetic field causes aurorae at its north and south poles. However, the effect is much greater and actually heats up its atmosphere, as discovered from mid-infrared observations at Subaru on MK.

"Auroras at Earth's poles (known as the aurora borealis at the North Pole and aurora australis at the South Pole) occur when the energetic particles blown out from the Sun (the solar wind) interact with and heat up the gases in the upper atmosphere. The same thing happens at Jupiter, but the new observations show the heating goes two or three times deeper down into its atmosphere than on Earth, into the lower level of Jupiter's upper atmosphere, or stratosphere."
[...]
""What is startling about the results is that we were able to associate for the first time the variations in solar wind and the response in the stratosphere - and that the response to these variations is so quick for such a large area," said JPL's Glenn Orton, co-author and part of the observing team."
