Scientific paper

Attention is given to two indices developed for the purpose of comparing the natures of various classes of comets: the Activity Index (AI), which measures the inherent magnitude increase in brightness from great solar distances to maximum near the perihelion, and the Volatility Index (VI), which measures the variation in magnitude near the perihelion. AI determinations are made for 32 long-period (LP) comets and for 14 short-period (SP). The range of values of AI is of the order of 3 to 10 magnitudes with a median of about 6. No fading with aging among the LP comets was found. No systematic change with period occurs for the VI index. Weak correlations are found with the gas/dust ratio of comets. No correlations are discovered between the two indices, nor of either index with near-perihelion magnitudes or orbital inclination.
