Title: Characterizing the energy drivers of the upper atmosphere of Uranus

Abstract: This program aims to identify the mechanism that drive the elevated temperatures in the thermosphere at Uranus - an unexplained phenomenon seen at all the gas giants. The temperature has perviously been observed to cool between 1992 and 2008, and we expected the planet to heat up again after 2007 equinox. Instead, surprisingly, in 2011 it was observed to continue to cool. This poses questions to what drives the temperature of the upper atmosphere, and by observing Uranus in late 2013 we can address these. In addition, the continuation of the long-term monitoring of Uranus’ upper atmosphere will shed considerably insight to the thermal drivers of this poorly understood planet.
