       ON THE PERIOD OF THE Ap VARIABLE HR 8861




    Photoelectric observations of the Ap star HR 8861
(=HD 219749=ET And) have been carried out at the Ege University
Observatory from June 1977 to December 1977, a total of 19 nights.
The observations were obtained in the u,v,b colours with the
48 cm Cassegrain telescope equipped with an unrefrigerated 1P21
photomultiplier.
    HR 8870 (=HD 219891) (6.4m, A2) and HR 8857 (=HD 219668)
(6.4m, K0) were used as comparison and check star, respectively.
    From Rakos' (1962) photometric observations, Rakos
(1962) and Renson (1965, 1977) give the periods as 2.604d, 0.723d
and 1.618d, respectively. However, none of these periods show
any agreement with my observations.
    Observations of four minima were received in u,v,b and
a new set of light elements of HR 8861 were determined as

    Hel.Min. = JD 2443337.4725d+0.49925d E.
