WAC phase angle ratio maps of the region where the 70 m diameter crater formed (centered at 22.352 °S, 320.270 °E). These ratios are created by creating two normalized mosaics at i = 30°, e = 0°, and g = 30°, as well as at i = 60°, e = 0°, and g = 60°. (a) The 30°/60° phase angle ratio was derived from observations before the impact. (b) The 30°/60° phase angle ratio was derived from postimpact observations. (c) The ratio of maps shown in (a) and (b) highlights the change in phase curve slope due to the impact event.
