A photometric test of rotation period for Uranus and time variations of methane-band strengths.
Abstract
Intermediate-band photometry of Uranus in the reflected solar continuum at 5508 and 7529 A and in the methane bands at 6190 and 7261 A has been analyzed for variations related to the rotation of the planet. No periodic variations were detected at a level of 0.003 mag, but a 1% increase in the strengths of the methane bands was observed over a 2 month interval.
