Observations of flare emissions in the optical continuum are very rare.Therefore, the analysis of such observations is useful and may contribute toour understanding of the flaring chromosphere and photosphere. We study thewhite light continuum emission observed during the X6.9 flare which occurred onAugust 09, 2011. This emission comes not only from the flare ribbons but alsofrom the nearby plage area. The main aim of this work is to disentangle theflare and plage (facula) emission. We analyzed the spatial, spectral andtemporal evolution of the flare and plage properties by analyzingmulti-wavelength observations. We study the morphological correlation of thewhitelight continuum emission observed with different instruments. We foundthat some active region areas which produce the continuum emission correspondrather to plages than to the flare kernels. We showed that in some cases thecontinuum emission from the WL flare kernels is very similar to the continuumemission of faculae.
