June–November 2008 light curves of BL Lacertae from UV to near-IR after correction for the host galaxy contribution, but not for the Galactic extinction. Data taken by the GASP-WEBT collaboration are plotted as blue circles, UVOT data as red triangles. The UVOT u, b, and v light curves have been shifted to match the ground-based U, B, and V ones (see text for details).
