                      WR 131

      The variability of this star (RA = 19h22m07s, D = +47deg03';
1900.0) was announced by R. WEBER in JO 43. No. 8 p.119. 1960.
He published 60 observations and suspected Algol type. From estimates 
on 127 sky patrol plates (JD. 243 6819 - 243 9028) we obtained
the preliminary elements:

      Min. JD (hel. ) = 243 7146. 546 + 4.56427day x E
      Max. 11.3mag pg; Min I 12.3m; Min. II 11.8m

      The following Table contains our epoch of minimum and
those obtained by WEBER and HUTH (Sonneberg),

      I thank Mr. HUTH for his observations.

          PHOTOELECTRIC MINIMA OF AB AND

      Three photoelectric minima of AB And, obtained at the Nurnberg 
Observatory in the years 1963, 1964 and 1965 show large positive
O-C' s against the elements in GCVS (I) and SAC 38 (II), respectively


      Min: JD 2435 075,400 + 0.331888day x E            (I)

      Min: JD 2436 109,57835 + 0.33188940day x E        (II)

     The new elements (III), published by W. QUESTER in IBVS
No. 190 represents our photoelectric minima very well.

      Min: 243 6109,57928 + 0.331 892 15day x E         (III)

      The following Table gives our minima together with the O-C's
resulting from formulas (I) to (III)
