Antoine, your post was very intriguing to me! I believe the 22 Feb shower you
mention is known as the "Delta Leonids" by IMO, peaking on 24 Feb: I was aware
that this shower was thought to be associated with asteroid 4450 Pan. And of
course, the relationship between the Geminids and Phaethon is well known.
But ALL the other asteroidal shower associations you mention are news to me!
For example, I thought the Ursids (whose peak is coming up soon, on 22 Dec)
were thought to be associated with Comet Tuttle! See, e.g., Gary Kronk's
"Meteor Observing Calendar" entry for this shower, on the Web:
http://comets.amsmeteors.org/meteors/showers/ursids.html
I'd be interested to hear any references you've seen to non-cometary parent
bodies for any showers besides the Delta Leonids and Geminids, Pierre!
Thanks, and clear skies,
Lew Gramer
