“…FACs in Saturn's auroral regions have previously been investigated in detail based on magnetometer data (e.g., Cowley et al, 2008;Hunt et al, 2014Hunt et al, , 2015Hunt et al, , 2016Hunt et al, , 2018Talboys et al, , 2011, but Cassini's orbit greatly limited our ability to characterize the acceleration region in more detail before the last low spacecraft passes across the auroral region.
