Vuver is a crater on the surface of Uranus' moon Umbriel. The longitude and latitude of its center are 311.6° and −4.7°, respectively. Vuver has a bright central peak, which is one of the few bright albedo features on Umbriel that really stands out against Umbriel's low albedo. (wikipedia entry)
A crater is a circular depression likely created by an impact event. On Umbriel they are named after dark spirits (individual).
Sorry, there hasn't been a good map made for this world yet :(
