We had an expert mathematician calculate from charts at what time the sun would be at it's highest point in the sky at 4.2 degrees west of the Greenwich Meridian. He told us that would happen at 13.19 - and that's exactly what time it was when the shadow fell across the notch!
Can I ask...did the mathematician work this out prior to and separately from your timings and the two results compared afterwards or did he give you a time and you worked from this? Also did you film this event...I'd like to see footage of it...not for critique or analysis but just out of curiosity.
