New VBLUW photometry of the S Dor type variables S Dor and HDE 269006 in the LMC made in 1979 and 1981 are discussed. S Dor has reached the lowest brightness in 1981 of the last 8 yr, but it is still far from the minimum. HDE 269006 was at minimum brightness. Temperatures are estimated for the central star and the envelope by fitting black body energy distributions to the VBLUW energy distributions. The agreement with spectroscopic results is satisfactorily, although Teff for the central star of S Dor, 0.7 mag below the maximum, seems to be much higher than for an early A type star as proposed by some spectroscopists for the maximum. Although there are no direct proofs of a variable central star, such a possibility should not be excluded.
Some basic properties of the shell of HDE 269006 are estimated.
