Scientific paper

Monitoring of four Wolf-Rayet stars (WR 22, WR 46, WR 86, and WR 93) in the VBLUW system of Walraven, each during a whole night are presented and discussed. Two of them appeared to be constant during the time of observing, viz. WR 22 and WR 93, in contrast with the other two stars WR 46 and WR 86. Their light amplitudes are 0m.075 and 0m.025, respectively, and the time scale for both amounts to ≡3 h. The second object became slightly bluer during maximum light.
