\begintext

In this 39th compilation of BAV results, photoelectric observations
obtained in the years 1998 and 1999 are presented on 115 variable stars
giving 172 minima and maxima. All moments of minima and maxima are
heliocentric. The errors are tabulated in column `$\pm$'. The values in 
column `$O-C$' are determined without incorporation of nonlinear terms.
The references are given in the section `Remarks'. All information about
photometers and filters are specified in the column `Rem'. The observations
were made at private observatories. The photoelectric measurements and all
the lightcurves with evaluations can be obtained from the office of the BAV for inspection.
