Watching the Sun much in the way that many people have in the past…..
At equinox the daily displacement of the Sun is at its greatest. moving past this towards the solstice sees a slow decrease in its rising and setting positions along the horizon. One question is how noticeable a change does this make from day to day, particularly with a long and distant sightline?
The following images have been taken from the summit of the Iron Age hill fort Castle Pencaire looking towards west Cornwall and Penwith.
There will be an image for many of the sunsets during isolation, I will try and update regularly, with the intention of demonstrating how visible the daily displacement is to someone making observations and watching the Sun. This is inspired by mayescreative.com #seventeensuns #watchingthesun HLF project which is revisiting the seventeen years that Schwebe made solar observations, which lead to his discovery of the solar cycle.
