All times are local (EET = UTC+0200)

11:30.
The Sun is behind the center of the upper part of the cloud. I was looking in SSE direction. Sofia is about half an hour past the meridian time, so local noon is around 12:30 (it was only a day before the solstice, so the additional sundial adjustment was about zero).

14:40.
I could not take pictures for three hours, because the Sun was apparently too close to the cloud. Meanwhile the cloud developed typical lenticular form. The slopes of Vitosha Mountain, 2190 m (7180 ft) are visible on the background, bottom-right.

15:20.
The cloud did not move essentially from the beginning until this last stage of its developing. At 16:30 there was no trace of the cloud.
