The homopause temperatures of 180–250 K for the 8 µm north-polar hot spot (8NPHS) of Jupiter are derived.
- class="label">•
CH4 mixing ratios at the 8NPHS are consistent with those in equatorial regions.
- class="label">•
Possible mechanisms for the relatively cool 8NPHS homopause are proposed.

Locally-fixed and transient but energetic auroral particle precipitation is a possibility.
