(a) polar projection of aurora with magnetic footprint track of Juno in light blue. The UV image was taken during the thick part of the track. The time interval of Fig. 1 corresponds to the blue box. The thick orange arc shows the direction to the Sun during the integration of the image. (b) Juno’s trajectory in blue shown in a magnetic reference frame. The thick part of the trajectory is for the time interval of Fig. 1. The gray lines represent the M-shells of 50, 40, 30, 20, 10, and 5 (JRM09+CAN1981). The dark red curve shows the 1-bar level of Jupiter’s atmosphere.
