Abstract We have obtained Gemini/GNIRS 3.3–3.4 μm spectra of Jupiter at 65o 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 of CH4 and C2H6. The observed locations of the brightest spots of the C2H6 and CH4 emissions at 65oN differed in longitude typically by 20o during this period. The peak emission intensities of these species showed large variations, with the highest intensities 3–4 times greater than the lowest intensities. In addition, the brightest 3-μm CH4 emissions and hottest temperatures at the 8CNPHS were significantly less than those at the 3-μm CH4 north polar hot spot (3CNPHS, Kim et al., 2015). Recently, Sinclair et al. (2019) reported a coincidence between solar wind dynamical pressure and the 8-μm brightening of the 8CNPHS. In contrast, we find lack of correlation in our data between the 3-μm hydrocarbon emission intensities at the 8CNPHS and the solar wind strength. We also find lack of correlation between H3 + intensities and the solar wind strength during the period. However, due to the limited observational data, it is too early to conclude whether this lack of correlation indicates that the solar wind activity induced no significant changes in local temperatures (<40 K) and/or mixing ratios of these molecules. Our observing period was close to the historic grand solar minimum. The detailed influence of the solar activity on the 3 and 8 μm brightness at the 8CNPHS is not quantitatively understood at the present time. Highlights Gemini/GNIRS 3.3–3.4 μm spectra of the 8-μm CH4 north polar hot spot (8CNPHS) of Jupiter were obtained. Four occasions during a five-month period in 2018 were observed. The variability of the 3-μm emission intensities of CH4, C2H6, and H3 + was studied. The peak intensities of these species showed the highest 3–4 times greater than the lowest. We find lack of correlation between the 3-μm hydrocarbon intensities at the 8CNPHS and the solar wind strength.
