Subradar point (west) longitudes of Europa and Ganymede at the epochs of 3.5 cm radar observations. The black lines represent our 2011–2024 observations, whereas the red lines represent the observations obtained in 1987–1991—the most recent and extensive set of published 3.5 cm radar results for the Galilean satellites (S. J. Ostro et al. 1992) prior to this work.
