Subj: Enquiry relating to the wide polar gnomon and its midnight overlap in
polar area
Hi all,
When studying the wide polar gnomon one inevitably encounters edge
changes to be respected. My special focus is on a horizontal dial
for a location with midnight sun. Around midnight the scale needs
two overlapping sections. I have designed a solution based on a
uniformly convoluted spider scale (see attached jpg (203 kB)).
My question: Is a comparable dial existing anywhere? My
web research produced only nil returns. The closest but not
relevant hit is the Longyearbyen
sun dial.
Kind regards
Helmut Haase
