We have obtained 3.3–3.4-lm spectro-images of Jupiter including CH4 and H3 + emission lines from both polar regions
at the Gemini North telescope. We find that the peak of the 3-lm CH4 northern bright spot is located at 200 (SysIII)
longitude, 20 west of the center of the 8-lm north-polar bright spot, and does not coincide with the 3-lmH3 + bright
spot. We derive high temperatures (500–850 K) from CH4 rotational lines on the bright spots of both polar regions,
above the 1-lbar pressure level, while we find cooler temperatures (
