The First Eclipsing Binary Observations at the Ulupinar Astrophysics Observatory Not Available
CCD Minima of Selected Eclipsing Binaries in 1999 Not Available
Photoelectric and CCD times of minima of several eclipsing binary systems We present several photoelectric and CCD minima observations of severaleclipsing binaries. Most of them are apsidal motion stars (or at leastcandidate ones).
OO Aquilae Times of Minima in 1993 from Visual Observations More than 250 visual observations of the eclipsing binary OO Aquilaewere made during the 1993 observing season. The data were used to find27 times of minima for this system. Most of them are low-accuracy timesof minima found by extrapolating from near-minima observations; six werefound by fitting a cubic equation to the data.
1987-1989 UBV Photometry of OO Aquilae Not Available
