This is a visual binary (A.D.S. 8148) with a period of 192 y, in which the companion is 2.7m fainter than the primary. The visual orbit has been derived by P. Baize (J. Observateurs, 35, 73, 1952) and his values of P, T, e, and omega were assumed. The quality classification refers only to the elements K and V0. Although the velocity variation is consistent with that expected, the scatter of individual observations is approximately equal to the derived value of K, and some caution in accepting the elements appears desirable.
