We report the possible detection of V4334 Sgr (Sakurai's Object) at 450 and 850 μm with SCUBA on the James Clerk Maxwell Telescope. The submillimetre photometry, combined with a 1–5 μm spectrum and 8–10 μm photometry obtained nearly contemporaneously, suggests that the submillimetre emission originates in material ejected during the 1995 event. The dust mass is a few×10-7 M⊙, the average mass-loss in the form of dust is few×10-8 M⊙ yr-1, and the integrated luminosity is log(L/L⊙)=3.66 for a distance of 2 kpc. The ejected shell had angular diameter ∼55 mas in 2001 August, and should by now be resolvable in the mid-infrared by 8–10 m class telescopes.
