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.
