Before a solstice Sun rose on June 21,brilliant Venus and an old crescent Moon posed togetherover Budapest, Hungary for this predawn skyscape .In the foreground the view looks across the Danube river from Buda to Pesttoward the dome and peaks of the Hungarian Parliament building.Low clouds are in silhouette against a twilight sky. But farenough above the eastern horizon to catch the sunlightshines another seasonal apparition on that solstice morning, noctilucent clouds .Seen near sunrise and sunset in summer months at highlatitudes, the night-shining clouds are formed as water vaporin the cold upper atmosphere condenses onmeteoric dust or volcanic ash near the edgeof space .
