COMMISSIONS 27 AND 42 OF THE IAU INFORMATION BULLETIN ON VARIABLE STARS Number 3948 Konkoly Observatory Budapest 29 October 1993 HU ISSN 0374 - 0676 TIMES OF MINIMA OF SOUTHERN ECLIPSING BINARIES Here are presented photoelectric minima for AG Phe and LT Pav. Observations were made at Cerro Tololo Interamerican Observatory in Chile^1 with the 60 cm Lowell Telescope, standard UBVRI filters and photon counting techniques. Kwee and Van Woerden (1956) method for determining times of minimum light was used for the observations of AG Phe while the sliding integrals algorithm (Ghedini, 1981) was used for LT Pav. The determined minima are listed in the following tables together with the standard deviation given in brackets in units of 0.0001d.
