On Saturday 30 June 2007 before sunset, weather conditions improved as announced. Venus could be spotted without instruments. Telescopic views were impaired by poor seeing. Saturn could not be seen at the telescopes, even using filters. At that time, there was an aircraft corridor in front of Venus and Saturn, hence the first picture in the gallery below – after drastic contrast enhancement, it shows Saturn at the upper left corner.
\nAs dusk was in progress, Saturn became a telescopic, then a binocular, then a naked-eye object. Wide-field images were taken – see second picture.
\nAfter 22h, Venus and Saturn were low in a rather dark, very turbulent sky. The third image was strongly enhanced in sharpness to show Saturn\u00b4s rings, and compressed in dynamic range to show some phase on Venus: this introduces some artifacts and also a \u00ab\u00a0Malevich painting\u00a0\u00bb aspect for the sky.
\nAs a nice surprise, seeing improved greatly during the evening. The Envisat satellite was seen with some detail, then Jupiter’s cloud bands, shadow of Ganymede and Great Red Spot (pale salmon, in fact) were clearly revealed. The Galilean satellites could be told from one another according to hue, apparent diameter and overall brightness.
\nTurbulence increased again while observing the companion of Antares and the rising full Moon.
\nBefore dawn, turbulence had decreased again, but there were thin clouds. Mars was thus seen as a subdued, reduced contrast disk definitely showing a phase, but no polar cap anymore, and only a hint of Terra Sirenum.<\/p>\n
