The cometary observation service is surveyed. Absolute magnitudes and other physical characteristics are given for the comets that appeared during 1965–1970. The general laws of cometary brightness, in particular the secular decrease in brightness, are discussed. Remarks are made about the standardization of cometary photometry.
