stable image,some moisture and moonlight does not bother too much,color darker bluish-green,
two more clear to Ecuador and N pole areas observed Greetings

Here are the last observations performed with the 254mm Cassegrain using
Very good images and sky transparency fair.
Some albedo variations are shown with the banding system well appearing.

Uranus was my main target for the 2 nights mission last week at the one meter
telescope. Conditions were correct that first night,but K1 was not visible
(that was the opposite the night after ). I could get many images in IR
685nm long-pass filter:
An animation attached (gif file) with images from dozens of individual videos
does not show any supsect spot moving with the rotation of the planet.
I made one attempt with a 50nm FWHM 889nm methane absorption band (large FWHM
because otherwise Uranus would have been too dim even with a 106cm scope). There
could be a suspect spot right at meridian and center of the globe (?):
Here are the rest of my observations on Oct. 4th with the one meter telescope
under less good conditions than the night before,but showing the storm
transiting with a position 5° higher than the predictions (220.5° L1,34.6°
planetographic latitude). Please note that the storm brightens when close to
transit (00h52.7UT image while transit was predicted at 00h38UT) and then fades
away. Also it seems of the same brightness as the polar area,while on earlier
images it was brighter.

Storm starts being visible:
the best image close to transit (00h38UT):

Here is Uranus on 2014/10/03 (2 sets + 1 animation) .
The seeing was fair and the transparency was bad.
