Dear sirs,here are the Jupiter images obtained yesterday,starting with average seeing and then with progressively degrading conditions.
The attached gif animation blinks CH4 727 and continuum 750,and is from additional datasets not included in the image panel.
Differences mentioned in my last message are seen,namely belt-zone and anticyclone contrast,
and presence of some deeper clouds.
Hint of polar hoods is present on the CH4 727 frame,and the continuum is better to evaluate small scale features at high latitudes.
The two smeared Io images in the CH4 727 frame (versus only one in the 750 continuum) is due to "symmetric sequence grabbing",
to provide better S/N ratio in the CH4 band filter,
but also to prevent JUPOS limb derotation artifacts that would become visible during image-ratio or image subtraction.
