Evening shelf cloud. Captured from our flat at Praha - Kačerov, Czech Republic, southwestward view. See also these two static images - resized original (out of camera JPG) image, and image processed from raw file (uncompressed ARW file).
See also the CZRAD radar loop (red dot indicating place and time of the timelapse above) and MSG satellite loop (ending with sunset, just before the timelapse was started).

Morning sky above Olifants River in Kruger National Park (or alternate site), from Olifants Rest Camp, South Africa (southward view). In Kruger Park (including fenced camps) you must not leave your tripod with camera unattended, otherwise Vervet monkeys or Baboons (present in most of places) may try to steal it, or at least damage it...

Sunrise above Letaba River in Kruger National Park (or alternate site), from Letaba Rest Camp, South Africa. As we are south of the Equator, the Sun rises at opposite angle than at the northern hemisphere. And the "drifting boulders" in the river (at the beginning of the sequence) are hippos.

Timelapse of the southern sky taken from Punda Maria Rest Camp in Kruger National Park (or alternate site), South Africa. As you can see from the timelapse, the night was rather bad, with some dissipating clouds spreading from the south (well seen in the lower right part of the movie). Unfortunately, it was the only nighttime timelapse I managed to take during our entire 10-day trip to the park. In the Kruger NP, it is forbidden to stay overnight outside the camps (for security reasons - wild animals), and all the camps have lighting - which makes night-time astrophotography there almost impossible. Also, we were in the park around the time of the full moon, so we only had dark skies on several last nights, for a couple of hours in the evening. The timelapse was taken from an upper terrace of our cottage there (the only place with an almost open view to the sky), which also was the source of the variable illumination of the nearby trees. Well, if you visit the Kruger NP, you are there for the animals, not for the night sky... Finally, the surroundings of the Kruger NP are quite light-polluted, as can be seen in the right (western) part of the timelapse.
See also the still image from the end of the timelapse sequence (19:37 UTC), Metop-C satellite images from almost the same time (19:30 UTC) - AVHRR channel 3 image and Night-microphysics RGB image, and MSG2 (IODC) satellite loops (12:00 - 23:45 UTC) in IR10.8, WV6.2 and WV7.3 bands, showing the clouds movement and high humidity at higher levels over the area. The green/red dot shows the location and time of the timelapse, southward view.
