Saturn dark oval May 8th

Hi All,

Imaged Saturn last night, targeting the dark oval in the NNTrZ.
Have 2 R, 2 RGB & 1 742nm IR data sets over a session of 90 minutes. The seeing was fair.



The dark oval is clearly visible in all data sets. In the first R & RGB images the bright spot that has been leading the dark oval in the NNTrZ is also visible but the distance between them is stretching out noticeably. I suspect the position of the bright spot, being a little further North, is experiencing the stronger winds in the jetstream of this region. I also note a bright spot in the NEB, just leading the dark oval.



Have also attached animations of the R & RGB data which show the movement of the dark oval quite well. Have also attached polar projections of all data.

Thanks for looking

Regards
Trevor
