A catalog of a sample of 220 periodic comets is presented with our ``best estimates'' of their absolute nuclear magnitudes HN = V(1,0,0). It includes either Jupiter family (JF) comets (defined as those with Tisserand constants T > 2 and perihelion distance inside Jupiter q < QJ), Halley-type comets (T < 2) and a few Centaurs comets (T > 2 and perihelion distance outside Jupiter q >QJ). This is an update of a previous version of the catalog (Tancredi et al. ). The catalog includes all the nuclear magnitudes reported after 1950 until January 2003 that appear in the International Comet Quarterly Archive of Cometary Photometric Data, the Minor Planet Center (MPC) data base, IAU Circulars, International Comet Quarterly, and a few papers devoted to some particular comets, together with our own observations. Photometric data previous to 1990 have mainly been taken from the Comet Light Curve Catalogue (CLICC) compiled by Kamél ().
An analysis of the distribution of nuclear magnitudes of JF comets is presented
in the following article: Tancredi et al.(,
"Nuclear Magnitudes and the Size Distribution of Jupiter Family Comets").
