Jupiter's Dawn Magnetosheath and Magnetopause as Measured by Juno

Juno's 53-day orbit, with its apojove at 112 RJ, has spent a substantial amount of time in the magnetosheath on the dawn side of Jupiter and crossed the magnetopause boundary more than a hundred times. Data provided by the Juno Magnetic Field Investigation (MAG) show that the magnetic field in the dawn magnetosheath drapes around the magnetopause in both the northern and southern hemispheres. We also show other statistical properties of the dawn magnetosheath, including plasma flow velocities, directions, and pressures. Over the past 18 months, however, Juno has only measured one full crossing of the magnetosheath, from bow shock to magnetopause, with its entire field and particles instrument suite active. We present the data of this magnetosheath crossing from June 24-25, 2016. On the dawn side of Jupiter, the magnetospheric rotation is in the opposite direction to magnetosheath flow, which encourages the growth of the Kelvin-Helmholtz Instability (KHI). We search for surface waves by comparing models of Jupiter's magnetopause with measurements of the magnetopause boundary normal, extracted from the MAG data using minimum variance analysis (MVA).
