Astronomical Data

The huge amounts of data I collected are probably of little direct interest. However it was very useful to help me visual the lighting changes over the day/months . The most difficult part was to learn to understand what all those numbers really meant not to find them on the net. It may be the same for you. There is an excellent tutorial on Positional Astronomy on the net if you are interested. I collected sun data in advance for the whole of the exhibition. Here I included only the data for the equinox itself.
