It represents a portion of the stars observed by participants in the AAVSO's eclipsing binary program since 1975 and continues the listing of minima published in Observed Minima Timings of Eclipsing Binaries Number 1 and Number 2 (Baldwin and Samolyk 1993, 1995). Except where otherwise specified all minima are determined from visual observations reduced by the authors using a computerized tracing paper method. The tracing paper software was written specifically for this purpose by Ron Baldwin and Gerard Samolyk. In instances where fragments of eclipses are observed during different cycles, the data points are reduced to heliocentric phase and combined into a single lightcurve for the tracing paper process. In these cases, the listed time of minimum is the eclipse nearest to the midpoint of the observing interval that corresponds to the calculated phase of minimum light. A footnote is added to these listings indicating the observing interval in J.D. Some photoelectric and CCD observations were reduced by the observers using the method of Kwee and Van Worden (1956). The standard error is included in a footnote in each of these cases. Linear elements in the General Catalogue of Variable Stars (Kholopov et al. 1985) were used to compute the O-C's. All elements used in this publication are listed in Table 2. The number of observations used for determination of each time of minimum is given under N. This work is sponsored by the AAVSO with Marvin Baldwin acting as program coordinator. The O-C diagrams accompanying the minima listings represent not only the minima tabulated here but also all previously published minima associated with the AAVSO program. The years spanned by these diagrams are listed by star in Table 2 with the second column giving the year of the earliest observation appearing in the diagram and the third and fourth columns listing the earliest and latest year of the minima tabulated in this publication. Observers contributing data used in this publication are listed in Table 3. Their dedicated efforts are greatly appreciated. Marvin E. Baldwin Gerard Samolyk 8655 N Co.
