Saturn August 7th 2023

Imaged Saturn August 7th, have data covering 3 hr 1 min of Saturn rotation. Have good 685nm IR data, very good CH4 data, fair R data but poor G and B data so a rather ordinary RGB.
Note a particularly interesting feature consisting of a v-bright elongated spot just below the ring shadow with an accompanying bright linear feature just below it. I previously captured this structure in my July 24th data. All data has been uploaded to PVOL with links here to the animations.

Detail resolved in these data.

A v-bright elongated feature in the EZ at approx Lat+3.0 L1 206.6 resolved in IR data.
A bright elongated spot on the edge of the ring shadow at approx Lat-18.3 L1 192.2 resolved in IR data.
A bright elongated spot on the edge of the ring shadow at approx Lat-17.8 L1 291 resolved in IR and R data.
A v-bright extended linear feature centered on approx Lat-24.7 extending from L1 293.5 to L1 274 the best data resolves this into a v-close series of bright spots resolved in IR data.
A bright linear feature is seen mid SEB from limb to limb including a brighter section at approx Lat-31.6 L3 35.3 to L3 9.0 the best data resolves this into a v-close series of bright spots resolved in IR data.
A bright oval in the STrZ impinging up into the SEB at approx Lat-29.5 L3 310.4 resolved in R data.
The long lived red spot at approx Lat-55.6 L3 80.9 resolved in IR data.

Incredible detail in those IR shots. Quite a range of features. Can I ask what program you use to pinpoint such precise coordinates for these features?

I don't know about an "ordinary" RGB, this is a fine representation of Saturn. Nice work, as always!

Thanks very much Dave, I measure the co-ordinates in WinJUPOS. For best accuracy the outline needs to be very accurately positioned. I increase the gamma until the moons that are in the field become visible and adjust the outline until the moons coincide with there positions from the outline.
