The source has a spin-down age of 5.5 Myr, yet still has a magnetar-like magnetic field of B~1.5x10^(14) G. Here, we propose deep XMM-Newton and HST UV observations to detect or place physically constraining upper-limits on the temperature of hot spots and the full surface thermal emission from this interesting object. These observations will test, and help to significantly constrain, magneto-thermal evolution models in a parameter space where few data points currently exist. HST will observe the target in Earth's shadow using the SBC/FP125LP filter, for the remainder of the orbit the source will be observed using the F140LP filter. The HST and XMM observations do not need to occur simultaneously. We expect the impact of the reduced gyro operations to be minimal outside of the schedualability of the observations. If possible, we prefer for the visits to be seperated to allow for the SBC camera to cool down providing a lower backgroud and increasing our sensitivity, as this is expected to be a very faint target.
