The image was taken by Regina Valkenborgh, who began capturing it towards the end of her MA Fine Art degree at the University of Hertfordshire in 2012. It shows 2,953 arced trails of the sun, as it rose and fell between summer and winter over a period of eight years and one month. The dome of Bayfordbury’s oldest telescope is visible to the left of the photograph and the atmospheric gantry, built halfway through the exposure, can be seen from the centre to the right.

Regina had dit niet als doel toen ze haar bierblikje met een klein gat erin neerzette. Ze was ‘m gewoon vergeten en 8 jaar later werd het door David Campbell gevonden en dit is het resultaat. En het is meer dan geweldig.
