The R image (with no IR) stills shows a brightening on the north pole despite reversed orientation from my set taken on 31th august.

Please find attached an observation of Uranus from last night. We had some very dark and transparent skies last night, indeed I can't remember a night this transparent in Leicester for many years- it was hard to believe the city was only three miles away to the north! Seeing was also rather good and I was able to use powers of x312 and x400 to examine the Uranian disk.

There seemed to be a number of subtle features on display. The first thing that struck me was that the colour of the planet might not have been quite as distinct as last time, certainly there seemed to be a more greyish component to the cyan hues. There also seemed to be be a somewhat darker greyish belt and a lighter region beyond that.
