    I had exceptional seeing for this capture of Jupiter. I made 9 RGB runs and integrated them in the usual way, derogating with WinJUPOS.
    The great seeing has meant the feature resolution is exceptional from pole to pole.
    There are two interesting and persistent white ovals almost directly north of the GRS. The first way up north, in fact to the north of the NNTB is designated NN-WS-6 and the other, which formed in 1997 is in the NEB and is designated the White Spot Z (WSZ). There is a small dark red barge in the North Temperate Band north (NTBn).
    It remains to be seen whether the somewhat green coloured circular feature to the east (right) of the GRS will move across to impact it. These event have previously led to flakes or chips of the GRS breaking free and being spun out.
