Greetings All!

Here's an observation I made of Uranus on the 29th September. The disk was fairly uniform in brightness- the EZ seems to be the same intensity as the rest of the disk. There was a subtle darkening in the southern hemisphere.

Best wishes,
-Paul.

Like you said, the difference with your other sketch of Uranus is great. Has the planet really changed or are there other reasons (sky?)?

At the moment, I am not sure whether the change is real or not. I am awaiting observations from other people. I know Pete Lawrence captured a bright EZ earlier in the month, so when I've got everyone's obs in, I can compare.

Paul,

An excellent observation of Uranus. It is not unusual that the bright zone over the equator may have diminished in intensity considering that Uranus has a dynamic atmosphere and has exhibited changes over time (as imaged by the Hubble Space Telescope (HST) and amateurs around the world). It will be interesting to compare your excellent observation with that of other observers. Thank you for sharing it with us all.

Carlos
