Thermal lightcurve of 8P/Tuttle as seen from the Plateau de Bure on 8 January 2008. We used our standard set of parameters for the thermal inertia (I = 0), the beaming factor (η = 0.7) and the emissivity (ϵ = 0.95). The shape model is that of 8P/Tuttle derived from Hubble Space Telescope observations (Lamy et al. 2008; Lamy et al., in prep.). The lightcurve has been phased relatively to the radar observations of Harmon et al. (2010), performed  ~10 rotation periods earlier. The maximum (resp. minimum) flux corresponds to the emission of a spherical nucleus of 2.8 km (resp. 2.5 km). The horizontal thick solid line corresponds to the observation time at Plateau de Bure (2 h long).
