Abstract
Activity and mass distribution of the Geminid meteor shower of 1996-2007 from observations by a forward-scatter radio system operating along Bologna-Modra baseline are analyzed and discussed. Global activity curve for overdense echoes of durations ≥ 1 s and ≥ 8 s depicts two distinct peaks at solar longitudes 261.7◦, 262.3◦ and 261.9◦, 262.3◦, respectively. Larger particles are concentrated more to the centre of the stream and slightly shifted towards the descending branch of the stream activity. The mean mass exponent of the Geminids is 1.73.
