INTRODUCTION
This compilation contains 660 minima timings of 50 eclipsing binary stars.
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 9.
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 V1315 Aql, DV Cep, and EF Ori, the linear elements in
the 1985 General Catalogue of Variable Stars (Kohlopov et al. 1985) (GCVS)
were used to compute the O-C values.
In the case of V1315 Aql, no period has been established in the 1985 GCVS.
Lewis Cook observed this star intensely for two months to obtain the times of
minima listed in this document. The following light elements have been
calculated for this star by applying a linear regression to these observed
times of minima.
JDmin = 2453199.9643 + 0.1396907 E
No linear elements for DV Cep are listed in the 1985 GCVS. For this
publication the linear elements by Frank and Lichtenknecker (1987) are used.
It has been determined that the period listed in the 1985 GCVS for EF Ori
(3.7012d) is not valid. The light elements used in this publication were
calculated using the observed times of primary minima listed in this
publication.
JDmin = 2452350.592 + 1.6194474 E
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://ftp.aavso.org/monographs/eb/).
Observers contributing data used in this publication are listed in Table 3.
Their dedicated efforts are greatly appreciated.
