Comments: Imaged Saturn August 15th targeting a transit of the long lived red spot. This was an extensive session covering 3 hrs 53 min’s of Saturn rotation. Many features were resolved from the North Polar region to the South Polar region including a new SEBn feature. Detail resolved in these data. A compact bright spot at approx Lat+65.1 L3 11.1 resolved in IR and R data. A v-bright linear feature in the EZ centered on approx Lat+1.3 L1 122.7 resolved in CH4 data. A slightly elongated compact bright spot just below the ring shadow at approx Lat-18.1 L1 199.2 resolved in IR and R data. A very extensive bright v-linear feature has formed in the SEBn, this was not in my extensive data from the previous day or in any of my other previous data. It is only visible in the R data and there is significant contrast between the normally dark SEBn and this new feature particularly at the Westward end of the bright feature. This feature is centered on approx Lat-28 and extends from approx L3 346 Eastward with the brightest section of it to L3 322. It is intriguing to blink the IR / R image pairs s2023-08-15_13-56_ir_tba, s2023-08-15_14-04-54_r_tba then s2023-08-15_14-25_ir_tba, s2023-08-15_14-34-54_r_tba and then s2023-08-15_14-56_ir_tba, s 2023-08-15_15-05-48_r_tba. This feature is only resolved in the R data and thus is also seen in the RGB data. It is not resolved in the G or B data but I have also uploaded that data on this occasion for future reference as this feature evolves. A bright spot is resolved in the SEBZ impinging up into the SEBn at approx Lat-29.1 L3 256.4 rsolved in R data. A bright spot is resolved in the SEBZ impinging up into the SEBn at approx Lat-29.1 L3 11.8 resolved in R data. A bright spot is resolved in the SEBZ at approx Lat-32 L3 317.4 resolved in IR data. The long lived red spot is resolved at approx Lat-55.9 L3 55.7 resolved in IR and R data.
