On January 15 2015 at 9:15 we marked a line of the Suns shadow on the wall. Just over a month later on February 17 2015 we marked at the exact same time in the morning. The shadow line of the Sun had moved 97cm down the wall. Due to how the Earth is tilted in the winter the Sun is lower in the sky. As Spring progresses the Sun gets higher in the sky as our part of the Earth tilts back towards the Sun reducing the length of the shadow.
