Imaging of comet 46P/Wirtanen was performed in the standard VRI filters on 10 and 11 November 1996 with the 1.0 m telescope of the South African Astronomical Observatory (SAAO). After proper processing and calibration, the images have been used to derive information about the isophote distribution, magnitude and colour indices. We observed a coma extending to at most ~5×10³ km. We derive absolute magnitudes of the coma for the different filters and the colours V-R = 0.18±0.17 and R-I = 0.39±0.16.Link to publication
