OBSERVATIONS ON THE QUADRANTID SHOWER

Abstract

During the passage of a shower of Quadrantids, Radar was used with a photographic recording system. At the same time the echoes were observed on an oscilloscope. Observations were made from 30 December 1959 to 8 January 1960. A high percentage of the total number of echoes was received on January 3 and 4. Among the signals received during these two days, those which can be interpreted as echoes from meteor trails are shown in a panoramic form. The distance is plotted versus the time, a given echo is represented by a segment, the length of which indicates its duration, according to the following convention: a point corresponds to durations smaller than 0.2 sec; length 1 mm to durations comprised between 0.2 and 1 sec; 2 mm to durations comprised between 1 and 5 sec; 3 mm to durations comprised between 5 and 10 sec; 4 mm to durations larger than 10 sec. The numerical data of these echoes appear in tabular form. (Author)
