            ON THE delta SCUTI STAR BD +43d1894    


Although Agerer, Fernandes, and Frank (1983; IBVS 2370)
have reported that BD +43d1894 is a new variable of delta Scuti
type from their observations, the variable was already
discovered in 1980 by Yamasaki, Okazaki, and Kitamura (1981;
Paper I) and was further studied by Yamasaki, Gonzalez,
Peniche, and Pena (1983; Paper II).
  Agerer et al. (1983) have derived the pulsational period
to be P = 0.097949d from their times of maxima and mentioned
that the period seems to be somewhat variable. It is found,
however, that their times of maxima can be well represented
with our ephemeris (Paper I)

   Light Max. - JD(Hel) 2444291.12521 + 0.0982747d E,      (1)

as shown in Table I.

-------------------------------------------------------

    Thus, we confirm that a mono-period for BD +43d1894 as
given in (1) is correct, and the variability of the period
suspected by Agerer et al. (1983) could not be detected
from our observations (Paper I, and Paper II).
