I finally got a copy of the 1985 Astronomical Almanac so I can now update the epoch information in my phase of the moon program (pom.c) that I posted earlier this week. I have included the #define statements from the beginning to the program that need to be updated. Even though the previous version of the program used a 1983 epoch, the accumulated error is small. --Keith E.
