        PHOTOELECTRIC MINIMA OF ECLIPSING BINARIES


	The following Table gives photoelectric minima obtained during 
the years 1978/79 at the Ege University Observatory, Izmir
(Turkey) and the Nurnberg Observatory (Germany). Minima of eclipsing 
binaries observed at both observatories 1960- 1977 were published 
in Astr. Nachr. 288,69 (1964); 289,191 (1966); 291,111
(1968) ; IBVS 456 (1970), 530 (1971), 647 (1972), 937 (1974), 1053
(1975), 1163 (1976), 1358 (1977) and 1449 (1978).
	The Table gives the heliocentric minima, two different O-C's,
the type of filter, UBV, the abbreviations of the names of the
observers and the type of the instruments used (Izmir: 48 cm
Cassegrain, Nurnberg: 34 cm Cassegrain, both with phototube 1P21).
	Abbreviations of the observers' names:

		Bo = G. Bode          Mi = F. Mittl
		Ch = B. Chwastek      Pl = E. Pohl
		Eb = J. Ebersberger   Rd = E. Roderer
		Er = A. Y.Ertan       Sb = R. Sendelbeck
		Gr = R. Grobel        Sn = S. Evren
		Ib = C. Ibanoglu      Tg = I. Thiering
		Kt = M. Kurutac       Tm = O. Tumer
		Li = B. Liebscher     Tn = Z. Tunca
		Me = T. Mertelmeier


    Remarks:
    O-C (I) . GCVS, Moscow 1969/70. or First or Second or Third
Supplement to the Third Edition of the GCVS. Moscow 1971, 1974
and 1976
    O-C (II). SAC 51, Krakow 1979
    The (O-C)'s for secondary minima (Min II) were calculated
on the supposition, that they are symmetric between primary
minima (if no special data are given).
    m : only the elements I or the elements II give secondary
minimum.
    The sign = between O-C (I) and O-C (II) indicates that the
elements (I) and (II) are equal.
