Scientific paper

We present results from post-periohelion CCD observations of 109P/Swift-Tuttle when it was at a heliocentric distance of 5.3 AU. From inspection of the image profiles, contamination from the coma is estimated to be 14%, and this direct detection of the nucleus was achieved. From the apparent magnitude we deduce a mean effective radius of re = 11.8 km if an albedo of 14% is assumed. An upper mass limit of 7 x 1018g is obtained if we assume a density of 1 g cm-3. We discuss the extent of active areas on the nucleus of 109P/Swift-Tuttle and estimate that approximately 3% of the surface is active.
