FW: analemmatic sundial

[Pace]

sorry....forgot the photo! :)     -----Original M  essage----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Pace Sent: Thursday, July 15, 1999 4:36 PM To: sundial@rrz.uni-koeln.de Subject: analemmatic sundial Hello sundialists...   I am thinking about building a large analemmatic sundial, the one where you use your own shadow to read the time.   In practice, the final result i want would be something similar to the dial I am attaching to this mail (its only a 6kb .jpg file)   I would like to ask some questions, if anyone would be kind to answer, i would be very grateful. What is the minimum major axis diameter of the ellipse to be constructed if the time has to be read clearly? I intend only to mark hour and half hour markings on the dial. How may I construct the analemma (as seen in the attached photograph) ? Programs like zonwlak dont seem to design analemmatic sundials.  How large has this to be? Finally, what would be the best way to lay out the ellipse and to make the markings on the ground. Looking forward to your insights..   regards Alexei Pace   Lat:  35°50'33"N Lon: 14°32'44"E   Marsaxlokk, MALTA Attachment converted: Macintosh HD:analemmatic.jpg (JPEG/JVWR) (000067D9)
