Abstract
The Juno spacecraft crossed Jupiter's bow shock and into the magnetosheath on 24 June 2016. It then went into 53-day polar orbits with its apojoves at 113 Jovian radii on Jupiter's dawn side. These orbits have given us a unique opportunity to survey Jupiter's dawn magnetosheath. Using data from the Jovian Auroral Distributions Experiment, the Magnetic Field Investigation, and the Waves Investigation, we have identified 91 magnetosheath crossings for a total of 48.2 days of data. We present the statistical properties of the magnetosheath plasma, including density, velocity, magnetic field strength, temperature, plasma beta, pressures, and Mach numbers. We then show correlations between these various parameters. We confirm the rotation of the magnetic field to align with Jupiter's spin axis and find that this rotation correlates with several of the plasma properties, including magnetic field strength and plasma flow velocity. Finally, we discuss how these results can affect magnetic reconnection and the Kelvin-Helmholtz instability at Jupiter's dawn magnetopause boundary.
