Abstract
The ninth magnitude star V1094 Tauri = DHK41 = SAO 76494 was discovered to be an eclipsing variable in October 1994. Subsequent visual and photoelectric observations were used to determine the period. This proved more difficult than first thought due to the system's eccentric orbit and its period being almost exactly nine days. Observations between October 1994 and January 1997 are presented. New elements are:

    Min. I = 2449701.7059 + 8.988487 x E,
with the secondary eclipse at phase 0.65. Details will be published elsewhere. Addendum, 2006: In IBVS No. 4168, revised elements with a corrected period were published by Kaiser et al.:
    Min. I = 2449701.7062 + 4.49407 x E +/- 0.0004 +/- 0.00005
