39. Würzburger Frühjahrstagung
The earth rotates within 23 hours and 56 minutes around its own axis. Stars rise and set. Jupiter rotates in 9 hours and 50 minutes around it's axis. Comets move in a few days across the sky. These movements are the ones I want to show by time lapse photography. 8 hours movement of stars on Mauna Kea are shown in 3 minutes in the video. You'll be surprised.
New Zealand
We were in New Zealand three weeks on the North and in the South Island on the way. We have changed between the island over the Cook Strait and total 3500 kilometers driven through a fascinating country. particularly impressive UFO clouds (altocumulus Lenticularis) we saw in the Mount Cook National Park. In winter we have fascinating lighting effects, the fabled Landscape enjoyed.
Altocumulus Lenticularis (Ac len)
Called the beautiful altocumulus clouds Lenticularis, or lens clouds or UFO-clouds I have observed in New Zealand. The clouds are stationary in the sky.
