      FURTHER COMMENTS ON THE PERIOD OF V 743 Cen

In the discussion about the period of V743 Cen by Geyer and
Vogt (I.B.V.S. No. 1172, 1976) the presented (O-C)'s are based
on a period of 0.10225435 days. Its value, rounded to six 
decimals, as was given in that paper, yields much larger (O-C)'s
for the recent observations, though it is close to the period
given by Kukarkin et al. (2nd. Suppl. General Catalogue, 1974).
    A further investigation of the observed maxima with the
"period finding program" mentioned in I.B.V.S. No. 1172 gives
another plausible slightly shorter period for this object,
though the standard deviation for the (O-C)'s is a bit higher.
In the Table below are listed the least square solutions for
the light elements of the two possible periods, as well as the
S. Dev. for the resulting (O-C)'s.

   Only future observations of this star can decide which period
is the real one.
