Abstract

Observations of the Quadrantid meteor shower in 1997-2004 by the BLM forward-scatter radio system for meteor observation carried out along two baselines, Bologna-Lecce (Italy) and Bologna-Modra (Slovakia), are analysed from the viewpoint of activity and mass distribution and results are discussed. The activity curves of long-duration echoes (≥8 s) and their variations indicate a filamentary structure of the stream. The width of the stream at a half-maximum rate level is less than half a day (5–11.5 h). The mass distribution exponent s in the period of the shower maximum shows significant changes in individual years, with a high contribution of larger particles in 1997 and small particles in 2001, 2003 and 2004.
