Solstice observing: A small group of Friends gathered in the summer twilight to watch 3 planets appear. Despite the nearly Full Moon, Mars shone brightly in the South and Jupiter in the West. Saturn was rather close to the Moon and dimmer. Red Antares twinkled in the thick lower atmosphere with blue Spice in the South West. The Moon was observed in the ETX and then Jupiter. The 10 inch tracked Saturn as as the sky darkened first Tutan then Tethys then Dione appeared. A good Summer Sky tour was also possible.
