Caption: Ephemeral lake observations in Titan's south polar region near (60S,150E). The blinking image shows partially filled lakes (outlined in cyan) disappearing between images obtained in December 2007 (Cassini pass T39) and May 2009 (T55). Models of the change in radar brightness suggest that the amount of liquid loss is ~1 m/yr, consistent with the analysis of shoreline recession at Ontario Lacus.
