Scientific paper

New and more accurate UBV magnitudes have been obtained for 106 stars with known proper motions in the field of the emission nebular M8. The color-magnitude diagram of the embedded cluster NGC 6530 consists of a main sequence from B1 to about B9 with a distance modulus of 11.4 mag. Spectral types earlier than B1 and later than B9 fall above the main sequence. Evidence is given that the so-called pre-main sequence of NGC 6530 is not related to this cluster but consists of field stars. H-beta observations strongly support previous results that many cluster members are intrinsic Be stars.
