It represents a portion of the stars observed by participants in the AAVSO's eclipsing binary program since 1976, and continues the listing of minima published in Observed Minima Timings of Eclipsing Binaries Nos. 1 through 10. Except where otherwise specified, all minima are determined from visual observations reduced by the authors using a computerized tracing paper method. Ron Baldwin and Gerard Samolyk wrote the tracing paper software specifically for this purpose. Most CCD observations were reduced by the observers using the method of Kwee and Van Worden (1957). The standard error is included in each of these cases. In instances where fragments of eclipses are observed during different cycles, the data points are reduced to heliocentric phase and combined into a single light curve 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 JD. With the exception of Z Dra and GU Ori the linear elements in the 1985 General Catalogue of Variable Stars (34) were used to compute the O-C values. For Z Dra the linear elements from SAC 68 (36) were used. For GU Ori the linear elements from JAAVSO Vol. 14 No. 1 (24) were used. 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. Times of minimum obtained electronically that have four-place accuracy are circled on the O-C diagrams. 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. The material in this monograph may be accessed electronically via the AAVSO web site home page (http://www.aavso.org). 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.
