Simultaneous time series of broadband images of two active regions close to the disk center were acquired at the Swedish Vacuum Solar Telescope. Dark faculae are detecte in images obtained as weighted intensity differences between both wavelenght bands. Maps of brightness temperatures were computed for the best pairs of images.
