Plasma Sheet Properties Observed by Juno at Jupiter

Using Juno's first science passes through the jovian system, we combine measurements from the fields and particles instruments on the Juno spacecraft to make a preliminary map of the properties in the plasma disk. Juno's orbit is particularly useful for exploring the variation in properties with latitude as well as radial distance (beyond 10 RJ). We compare basic plasma properties (flow, density, temperature, composition, magnetic field strength) as well as derived quantities (pressure, plasma beta, Alfven speed) with those from previous observations (specifically Voyager and Galileo) and estimate the flow of mass and energy through the system.
