MOON

Name:	MOON
Purpose:	Learn about Lunar Phases...entertainment.
Author:	Greg Spears with due credit/big thanks to Christopher Osburn, Lunar Outreach Services, for the lunar phase calculation engine.
License:	Freeware (pls see MIT License, below)
Notes:	Compiled in MS VC++ First project in C ... a big transition from assembly language (ASM). C became more mandatory than optional as astrophysics calculations in ASM became a little overwhelming. C is much more friendly for this. Prior to Chris Osburn's generous provision of the perpetual lunar phase calculation engine, I was calculating Lunar Phase @ 29.53059 days per Lunar Cycle (synodic month), and using the Farmer's Almanac for a start date. Using the PC's system time, graphical appearance was generally close enough to actual lunar phase, but the lack of precision always bugged me. A synodic month is actually anywhere from ~29 - 30 days, and gradually varies over months & years. Chris's code closed this precision gap, and now the graphical display is as accurate as any professional software tool, I reckon.
