Abstract

This report continues that given in JAAVSO 5, No. 1. The listing includes 693 observed heliocentric minima of 103 eclipsing binary stars derived from observations submitted by participants in the AAVSO eclipsing binary program. All are visual minima reduced by the writer using the tracing paper method. Except where otherwise noted O-C's and epoch numbers are computed using the linear elements given in the main listing of the 1969 "General Catalog of Variable Stars" without regard to additional linear or non-linear elements which might appear in the notes following the main listing and without regard to more recent elements which may be listed in the supplements to the catalog. The number of estimates used for each minimum is given under n.
