Research project on sunlight in relation to the movement of earth.
Concluding form: public action and lecture-performance.
Duration of research: May 2017 to October 2018
In my job as a museum guard I could observe and measure the movements of sunlight and shadows for a long period of time.
Small spots of light can give an indication of the earth's axial tilt, a symmetrical courtyard can serve as a sundial.
How do seasons wander, where does summer begin?
In museum's silence one can sense the rotation of the earth.
Calculation of solar noon:
By observing and marking the daily wandering of a shadow in the museum's yard over the couse of several days I was able to calculate the time of local "real" noon, or solar noon. Which is at 1:32 pm (daylight saving time).
On June 22 – one day after summer solstice – exactly at the moment of solar noon I installed a brass bar in the museum's courtyard marking the annual peak of the museum's roof shadow during summer solstice.
A report of my observations, experiments, insights and emotions during the development of the project.
