Andromedids/November Piscids:
I have seen slow meteors during this time of year from a radiant near the
"tip/point" of Triangulum for more than twenty years and I have always called
them Andromedids.
I have records of these meteors from 12 of the years 1984-2007 with 1993 being
the last "good" year when I saw 21 Andromedids over several nights.
Examples:
1984: Nov 15/16 8:35-9:10pm CST (35 minutes) 5 Andromedids (Ames)
1988: Nov 13/14 7:00-8:00pm CST (1 hour) 7 Andromedids (McFarland Park)
1993: Nov 8/9 8:00-9:00pm CST (1 hour) 5 Andromedids (McFarland Park)
I have also read the paragraph in the IMO Handbook for Visual Meteor
Observations 1989 p.168 about approximately where the Andromedid radiant should
be "these days". I'm rather inclined to continue to call them Andromedids.
They certainly aren't anything new.
