Conclusions • T58 4-point lightcurve allows us to place an upper limit of 0.2o on the waves present at southwestern Jingbo Lacus • T59 15-point, but less spectacular, lightcurve gives the first possible hints of wave activity on Titan – either changing wind activity or very-long-wavelength waves (but could still be clouds) • Future high-cadence observations with points every 10 seconds across a few hours of specular observation time could really nail wave properties and lake index of refraction & composition; see next talk.
