| Abstract: | Geminids and Quadrantids are probably observed for only about 100 years. Due to perturbations of their orbits rapid variations occur. A change in the Geminid rate profile can not be found from observations. Observations of Geminids and Quadrantids from Arbeitskreis Meteore are compared with Perseid results. Around their activity peaks we find an increasing number of bright meteors. At the same time the population index r decreases for Perseids and Quadrantids, while it increases for Geminids. From this behaviour we estimate the increase of the number density to fainter magnitude classes for the three showers. |
