Saturn April 6th 2019 in good seeing, my best data thus far this apparition.
North Polar Storm linear feature extending from limb to limb at approx Lat+64 degrees.
In places a chain of individual bright cells while elsewhere seeming to be continuous.
I measure individual bright cells extending from the F limb to be at,
approx Lat+63.9 L3 346.2, Lat+65.1 L3 333.1, Lat+64.6 L3 307.9, Lat+64.2 L3 281.3;
note the image I used to make these measurements was s2019-04-06_18-32_ir_tba the zoom function within WinJUPOS was set at 2.05.
The 685nm-Pass IR animation really highlights the linear component of the storm at approx Lat+64 but also hints at more widespread features between the Southern edge of the polar collar and the edge of the North Polar Hexagon.
In particular there appears to be a more diffuse bright cell very adjacent to the edge of the hexagon near the CM on the measured data set.
