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 6. 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. Some 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. CCD data obtained by Ronald Zissell of EX Dra were reduced by the observer using the mean chord method. 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 EX Dra, linear elements in the General Catalogue of Variable Stars (Kholopov et al. 1985) were used to compute the O-C's. In the case of EX Dra, the linear elements were calculated by linear regression using the times of minima listed in this publication. 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) or the AAVSO ftp site (ftp.aavso.org in /pub/monographs). 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.
