[Alexander Obukhov:Moscow,Russia]

The 16th report was performed using the 150mm refractor and 324-375x.
Sky conditions was transparency excellent and seeing very good in spite of
the planet elevation (27°).
Still clear north cap (according to HST orientation), the first feature
appearing, then banding structure and at last 2 brightenings/spots on the
EZ area. EZ was looking with the brightenings a a clearer line all along.
After 0H00UT moisture deposition occured sothat the 254mm cassegrain was
not used due to worst conditions (seeing less 4/10 in the 150mm) and the
presence of moisturing strongly present. Observations stopped.
Not a bad report in spite of the aperture in game.
