The possibility of using speckel imaging techniques to detect the motion of features across the disc in the 6091 methane band, and with more suitable image intensifiers, in the 7261 band is considered.Goody, R. MHarvard Univ.Goody, R.M. (1981). The rotation of Uranus. This volume....
Models of Uranus were computed which match J 4 with a 17.24-hr rotation rate as measured by Voyager 2. These models imply an atmospheric enhancement of H 2O, NH 3, and CH 4 of not more than about 30 times the solar value, and have a total planetary ice to rock ratio more than 16...
O The nebula rose in temperature as its speed of rotation increased. O Atomic particles in the nebula gave off more heat when they became energized. O The dust grains broke up into smaller parts, allowing more light from the Sun to reach the inner portion of the nebula. O As the nebula...
Uranus (jʊˈreɪnəs; ˈjʊrənəs) n (Celestial Objects) one of the giant planets, the seventh planet from the sun, sometimes visible to the naked eye. It has 27 satellites, a ring system, and an axis of rotation almost lying in the plane of the orbit. Mean distan...
Fast Rotation: Uranus has a rotation period of almost 17 hours and 14 minutes. This means that a day on Uranus lasts 17 hours and 14 minutes. The unusual tilt of the axis of rotation of Uranus has consequences on its rotation. At certain times of the Uranian year, one of the planet'...
This pattern and its time variations determine the instantaneous form and temporal behaviour of the magnetic field so produced. Instantaneous magnetic fields will usually exhibit in their broad-scale features approximate alignment with the rotation axis. This is borne out by observations of the magnetic...

The auroral emissions are highly variable, as recorded with IUE, and the rotational phase of Uranus is not known. The observations will therefore cover the extent of a Uranus rotation {17.29 hours}, and will be repeated one-half solar rotation later to allow for variations in the solar wind...
In the long-wavelength region, the spectra are relatively smooth with the broad S(1) H 2 collision-induced rotation line showing strong emission for Neptune. In the short-wavelength spectrum of Uranus, an emission feature attributable to C 2H 2 with a maximum stratospheric mixing ratio of 9 ...
