About the Author
John Clark Craig, author of many computer programming books for Microsoft, has also programmed solar algorithms for several of the world's largest solar energy projects, located all over the world. While developing control and monitoring software systems for these projects, John constantly searched for the best algorithms and improved code for determining accurate sun position. Most of the available documentation was not easy to use, with bits and pieces of algorithms here and there, mixed in with poorly explained terminology, and with very little guidance for translating to other programming languages. John vowed to write Sun Position as the reference book he wished he had all along, with easy to read and easy to translate code, check points, validation test cases and debugging help.

Without access to the code, the book is pretty much worthless since all the dialog is about the code and NOT about the astronomical origins of the code, which is Meeus's book "Astronomical Algorithms", among others. I have tried to contact the author about getting the code, but have been unsuccessful.
Craig follows up by providing step by step examples of each calculation into a Visual Basic program. Additional information is provided on setting up Visual Basic Express, and some common debugging tips are also included. This book is a sun-tracker's resource! It is a must-have for anyone working in solar energy, meteorology, atmospheric sciences or other related fields.

While the text is dry (as one would expect from such a technical subject) the biggest flaw, and why I rated this publication as I did, is that the author doesn't provide the code as a single package. He has the code broken into snippets and requires that the user/reader copy and paste those snippets (using individual url's) separately to create locally runnable copies. While the first half dozen snippets were merely annoying, the next dozen or so were just infuriating.
I assume that the author had a reason for such ridiculous behavior, but for the life of me I can't fathom what it would be.
