Wow!
I am so glad I joined this list...what terrific resources! I (gratefully) stand corrected! I think your sites are terrific and the analemma site in particular is a real gem. I strongly recommend everyone new to the list check them out. So forgive me but I am replying to the entire list. I have to go now, I need to do some calculations for a analemma-shaped gnomon!
