Evolution of clouds on Titan over 36 hours between November 4 and November 6, 2022, as seen by Webb NIRCam (left) and Keck NIRC-2 (right). Titan’s trailing hemisphere seen here is rotating from left (dawn) to right (evening) as seen from Earth and the Sun. Cloud A appears to be rotating into view while Cloud B appears to be either dissipating or moving behind Titan’s limb. Clouds are not long-lasting on Titan or Earth, so those seen on November 4 may not be the same as those seen on November 6. The NIRCam image used the following filters: Red=F200W, Green=F150W, Blue=F140M, Brightness=F210M. The Keck NIRC-2 image used: Red=He1b (2.06 microns), Green=Kp (2.12 microns), Blue= H2 1-0 (2.13 microns).
