Mars+Saturn dark spot - 2/3rd July

SPX350, PGRFlea3, Baader RGB filters. Mars F41.3 Saturn F34.5.

Seeing was predicted to be good but it was fair and variable. Mars is getting smaller with phase and albedo features seem less contrasty now.

Saturn had a moment of good seeing on Sunday 3rd for just half an hour preceded by some of the worst seeing I have seen with heavy waves of instability bending Saturn like rubber and making the black inbetween the rings and disc disappear completely in turbulent defocus.

Saturn has a dark spot in the North Pole region shown in the GIF

Regards, John.

Mars may well be getting smaller John but you are still producing very impressive results, love the animation.

Have had a lot of unstable weather passing through for the last month or so and can well relate the gyrations of Saturn's rings but you have some nice data here. The dark spot on the edge of the Polar collar is the long lived Cyclone I have been tracking since March 2014, well done on resolving it. I also had reasonable seeing July 3rd and have a CM transit of the Cyclone. Looks like this week is back to cloud and showers passing through out here.

Regards
Trevor
