Jim: I was googling around and found this python code: https://garage.maemo.org/plugins/scmsvn/viewcvs.php/trunk/mclock-src/usr/lib/mClock/sun.py?root=mclock&rev=2&view=markup and this IDL code (which should be straightforward to convert to python): http://www.dfanning.com/programs/terminator_map.pro HTH, -Jeff P.S: I'd love to see what you come up with, so drop by sometime (it seems we're in the same building!) > ------------------------------------------------------------------------ > > ------------------------------------------------------------------------- > This SF.net email is sponsored by: Microsoft > Defy all challenges.
