Comments: Saturn July 3rd 2021, have mostly good data covering 2 ½ hours of Saturn rotation with the best of it being very good. There remains quite wide spread but low contrast activity within the EZ. It is characterised by a linear series of bright structure, spots, very near the border of the EZ and NEB along with another linear bright feature with the occasional plume further south near the ring shadow. Between these bright features snakes a dark linear feature. Due to the significant negative (westward) drift relative to the direction of rotation along with the likely short life of the brightest plumes it is quite difficult to try and track individual spots. The 685nm IR and RGB polar maps well define the extent of the bright linear activity along the border of the EZ with the NEB very well defined in the IR polar animation. I also note a bright spot best seen in RGB and G at approx Lat+27.7 L3 104.9
