Hi All,
Imaged Saturn April 2nd 2022 in quite reasonable seeing for the altitude. Have reasonable data at all wavelengths with data from this session covering 67 minutes of Saturn rotation. These data include 3 x 685nm IR data sets covering 56 minutes of Saturn rotation which were used to create a IR animation. Have also 2 x R channel data sets covering 25 minutes of Saturn rotation which also were used to create a R channel animation. Have 1 x RGB along with 1 x CH4 data sets.
Have created polar projections of the RGB and one of the 685nm IR data sets. The IR polar projection shows that currently there is very little difference in contrast between the north polar hexagon and the region immediately surround with regard to IR but the RGB polar projection looks promising with regard to the contrast between the hexagon and surrounds so I think with better data later in this apparition further measurements of the hexagons vertices may be possible with the RGB data. These data reveal very little in the way of discrete small scale atmospheric detail but that will change with better data.
Note: All data from this session has been uploaded to the PVOL database.
Have attached links to the IR and R animations from PVOL.
