Uranus Image 2014/11/21(UT)
Stanislas Maksymowicz (254mm SC)|
My last report about Uranus performed last 21st is sent for your attention.
Average conditions to bad, but with few times good images during few
seconds were noted.
Indeed the contrast are considerably enhanced, I tried to respect the
respective albedo levels.
Under yellow light, the pattern was the more interresting. Still the
clearing in the temperate band exhibiting in appearance 2 dark boundaries
with albedo variations, a notch being at the northern one in relation with
a brightening near the CM and on the clearing temperate zone (but not
attributed as a spot because we donot know if spotting stays here, donot
consult the ephemeris published here and elsewhere). EZ was not noted.
Polar cap was captured still with a dark boundary, the clear collar near
the cap area was not seen contrasted as previous observations.
South polar regio near the limb were seen clear.
