Scientific paper

The spectral types of 20 stars in the Blanco 1 open cluster (Zeta Sculptoris) are reported. Spectral classification in the MK system was performed on the basis of 125-A/mm dispersion spectra obtained with a 0.9-m telescope and a Cassegrain spectrograph. Of the stars classified, one classical Am star, one peculiar star with a weak K-line and one Ap star with marginal Si II lines enhancement were found, while the star Zeta Scl itself is observed to be a main sequence object and thus probably a foreground star. An H-R diagram of the cluster is also presented, and other probable members and nonmembers are indicated.
