Temporal variation of the 3-micron hydrocarbon emissions at the 8-micron north polar hot spot of Jupiter: Comparison with solar wind activity

Kim, Sang Joon; Yung, Yuk L.; Miller, Steve +5 more

We have obtained Gemini/GNIRS 3.3-3.4 µm spectra of Jupiter at 65^o North latitude over a range of longitudes roughly centered on the 8-µm CH₄ north polar hot spot (8CNPHS). The spectra were measured on four occasions during a four-month period in 2018, in order to search for variability of the 3-µm emissions…
