        SPECTROSCOPIC OBSERVATIONS OF V389 CYGNI



   Hoffleit (1977) has recently called for intensive new
spectroscopic and photometric observations on V389 Cygni. This
star was on the spectroscopic program of the David Dunlap 
Observatory from 1971-1974. During that time about 100 12Angstrom/mm
spectrograms were obtained. The analysis of this material is
still underway, but it is possible to make a few preliminary
comments.
   Periods shorter than the 3.3d period found by Young are
not present. The 3.3d period is present in our data set, but the
scatter about the velocity curve is enormous considering the
quality of the spectra - vsini < 15 km/s. However, multiple
plates taken on a single night do not show this scatter. They
are found to fit the mean velocity curve well provided a 
different V0 is adopted for each night. I have therefore concluded
that the system is triple. The long period may be ~150d,  but
periods of ~110d and ~270d are also possible.
