Titan: Visual + IMS (2)

In the December (2) mosaic, a North Polar hood that is bright at 5 microns is visible. Its composition is unknown.
The North Polar hood is barely seen in the October (1) and January (3) data.
Visible in the October and December images just South of the Equator is Tui Reggio, a Region nicknamed the "chevron". This Region is very bright at 5 microns and is among the brightest features on Titan at that wavelength.
Tui Reggio is thought to be a surface deposit, probably of volcanic origin, and may be water and/or carbon dioxide frozen from the vapor.
The December flyby data show that the western margins of Tui Reggio have a complex flow-like character consistent with eruptive phenomena.
