                    THE PERIOD OF THE MAGNETIC
                         VARIABLE HD 8441


    HD 8441 (alpha=1h21m23s, delta=+42deg53') is a magnetic variable
 star of spectral type A2p.  Measurements of magnetic field
 intensity are given in Babcock's catalogue of magnetic stars
 (Ap.J. Suppl. 3, 1957, star no. 3). From these measurements
 a period of 2.9632d for the magnetic variations has been found.

                          [FIGURE 1]

    It should be noted that this finding again confirms the
 suggestion mentioned in a recent paper (Steinitz, B. A. N., 17,
 504, 1964) that perhaps all magnetic stars are periodic.
