(meteorobs) Aries-Triangulids Notes
I just wanted to mention a few notes about the Aries-Triangulids that
may be of interest to NAMN observers. One question I've been asked is how
did I notice enhanced activity on September 12th 1993? Well, it was partly
luck, but it was also because I was facing the Southern Piscid radiant,
which was nearby, when many other observers were facing the Delta Aurigids
radiant. Gary Kronk is correct when saying that the activity from the A-T
area was greater in 1993 than 1994, or last year. In 1994 I was focused on
the A-T activity and saw about 4 per/hour, when in 1993 I was not looking
for meteors from the A-T area, and still saw about 6 per/hour. Yes, I may
have missed a few too in 1993, as I reported 17 sporadics and a fireball the
last hour!
Now about the radiant(s). I think there may be a complex of radiants, but
much more data is needed to determine this, but my gut feeling is that there
are two princple branches, a Northern and a Southern one, and that the char-
acteristics of them are different. I think that the Northern branch is rich
in faint meteors (the alpha Tri branch), and the Southern branch has brighter
average magnitude. The observations of Malcom Currie and Bob Lunsford respect-
ively in 1994 support this, as well as my own observations and recollections.
