  We present mid-infrared spectroscopy of Jupiter's mid-to-high latitudes using
Gemini-North/TEXES (Texas Echelon Cross Echelle Spectrograph) on March 17-19,
2017. These observations capture Jupiter's hydrocarbon auroral emissions
before, during and after the arrival of a solar wind compression on March 18th,
which highlights the coupling between the polar stratosphere and external space
environment. In comparing observations on March 17th and 19th, we observe a
brightening of the CH$_4$, C$_2$H$_2$ and C$_2$H$_4$ emissions in regions
spatially coincident with the northern, duskside main auroral emission
(henceforth, MAE). In inverting the spectra to derive atmospheric information,
we determine that the duskside brightening results from an upper stratospheric
(p < 0.1 mbar/z > 200 km) heating (e.g. $\Delta T$ = 9.1 $\pm$ 2.1 K at 9
$\mu$bar at 67.5$^\circ$N, 162.5$^\circ$W) with negligible heating at deeper
pressures. Our interpretation is that the arrival of the solar wind enhancement
drove magnetospheric dynamics through compression and/or viscous interactions
on the flank. These dynamics accelerated currents and/or generated higher
Poynting fluxes, which ultimately warmed the atmosphere through Joule heating
and ion-neutral collisions. Poleward of the southern MAE, temperature
retrievals demonstrate that auroral-related heating penetrates as deep as the
10-mbar level, in contrast to poleward of the northern MAE, where heating is
only observed as deep as $\sim$3 mbar. We suggest this results from the south
having higher Pedersen conductivities, and therefore stronger currents and
acceleration of the neutrals, as well as the poleward heating overlapping with
the apex of Jupiter's circulation thereby inhibiting efficient horizontal
mixing/advection.
