It is Solstice time!
This is my current Solargraphy image taken from summer solstice to winter solstice.
The bright lines are the days of the year written by the sun on the sky.
The upper lines are created at Summer, and the lower ones at winter.
The gaps in the lines means that there where cloudy periods at that time of the year.

The image was taken at Budapest, Hungary,
I used a plastic drain tube with 11cm diameter and 23 cm height.

Happy Solstice to everyone!
