Hi all,
My comments on the unusual sundial:
Could there be another disk (Hour Disk) that is above the disk that is
shown in the photo. And this hour disk is rotated by the HOUR ANGLE ARC
(the HOUR ANGLE ARC as shown in Fer j. de vries's email and image
Image1.gif). With the pointer at the top indicating the hour when:
2. Move Hour angle until a circular sunspot is formed on the globe.
Question:
Is the top rod a pointer and has a sharp point or has the rod been broken?
