We report on accurate BVRI photometry for the two Uranus irregular satellitesSycorax and Caliban. We derive colours, showing that Sycorax is bluer than Caliban. Our data allows us to detect a significantvariability in the Caliban's light-curve, which suggests an estimated period ofabout 3 hours. Despite it is the brighter of the two bodies, Sycorax does notdisplay a strong statistically significant variability. However our data seemto suggest a period of about 4 hoursComment: 17 pages, 2 eps figures, in press in Astronomical Journa
