Scientific paper

Strömgren four colour and Hβ photometry has been obtained for 39 early to mid-B stars in the young southern cluster NGC 3766. The cluster contains an unusually large number of Be stars, the proportion between magnitudes 6.5 and 11.5 being about 30 per cent. Estimates from both uvbyβ and UBV data indicate a reddening E(b-y) of 0.15 mag, corresponding to E(B-V) 0.20. The distance modulus obtained from both photometric systems is 11.4, giving a distance of 1.9 kpc.
