dc.description.abstract	Photoelectric magnitudes and colours in the UBV system have been determined for 101 stars in the field of NGC 6530. The interstellar reddening across the cluster varies from 0.25 to 0.48 mag, with an average value of 0.35 mag. The distance modulus to the cluster is estimated at 11.3 mag and age of 2x10⁶ yr is ascribed. The cluster luminosity function is compared with the general luminosity function and the initial luminosity function. Star numbers 304 and 338 are in the early stages of their evolution while star numbers 171, 284 and 338 are probably variables.	en_US
