Scientific paper

Recent photoelectric measurements of HR 4668 are used to correct earlier
estimates of the object's orbit. The first orbital calculations were
made in 1936 using eight Lick spectrograms taken in 1918. A total of 55
radial velocity measurements have now been made and an orbital period of
within 0.4 days of 1314.3 days has been estimated.
