Abstract
We present and discuss VBLUW photometry (Walraven system) of five supergiants in the LMC. For one well-known variable, the hypergiant R 59 = HDE 268757 (G7 Ia+) also Hipparcos photometry and numerous visual observations are available. The second variable is HDE 269612 (F0 Ia), and a third one is HDE 268822 (F6 Ia). Two F6 Ia supergiants turned out to be constant: HDE 269355 and HDE 270025.
Partly based on observations obtained at the European Southern Observatory at La Silla, Chile.
