             NEW ELEMENTS FOR SS Ari
	     
      Observations of SS Ari made by BAV-members in the
years 1965 to 1968 show large positive and increasing O-C
against elements given by E.N. KRAMER in Astron. Circ. 79,
9 Moscow 1949:

     Min = JD 2430 948.318 + 0d405 989 7 . E .

The well observed minima (s.Table) - lead to the provisional
elements

     Min = JD 2439 028.395 + 0d405 997 02 . E .

These elements are instantaneous; residuals are given in
the Table as O-C2. They represent the BAV-observations well,
but the starting point of KRAMERs elements is badly represented 
(O-C_2 = +0d076). Therefore a change of period is
supported.
