Fig. 2: Voyager 2 in situ measurements of solar wind conditions at Uranus’s orbit.
From: The anomalous state of Uranus’s magnetosphere during the Voyager 2 flyby
a–d, Voyager 2 crossed Uranus’s orbital path from day of year (DOY) 290 of 1985 until DOY 158 of 1986. This corresponds to Uranus’s perihelion and aphelion heliocentric radial distances (r) of 18.28au and 20.09 au, respectively. This figure is in the same format as Fig. 1. The solar wind velocity (a), solar wind density (b), solar wind dynamic pressure (c) and estimated expected magnetopause subsolar standoff distance (RSS) at Uranus (d) are shown. The Uranus flyby (from first to final bow shock crossing) is represented by the dashed vertical lines and data from that time period is not shown and not used for this analysis. The horizontal dashed lines show the Pdyn and RSS that were observed by Voyager 2 moments before crossing Uranus’s inbound bow shock on 24 January 1986.
