Zhihui Cao,Haifeng Sun,Ning Zhang,Xiang Lv17 Lyrids are found in the database and the stream mean orbit is derived. The shower radiant is compact, of a size 2°?×?1.5°. Applying a stricter limiting value for the Southworth-Hawkins D-criterion, two distinct filaments in the stream, on a short and a long period orbit, are separated. To confirm

The strong 2006 Orionid return with a very low population index (.?=?1.6) and a peak ZHR of 60 (about 2.5 of the average peak strength) resembled meteor showers connected with the returns of resonant meteoroids. An investigation of data dating back to
