ESO 511-G030 optical-UV SEDs derived using XMM-Newton and Swift data (dark green). The corresponding least squares fits are shown as straight dashed lines. XMM-Newton and Swift data are in blue and dark green, respectively. The solid, thick black line is the average SED by Richards et al. (2006) for Type 1 objects in the SDSS. The vertical dashed line is at logν_* = 15.08, corresponding to 2500 Å. We noticed a remarkable change in spectral shape from the 2007 observation compared to the later ones.
