Re: (meteorobs) Re Observations Sth Tau, Orionids, Pup Velids 2nd Oct 1997
Adam>>Reporting some observations made a few nights ago at one of our country
observing sites. Rates were good as were the Southern Taurids. The
Puppid Velid comples also presented a few meteors for us.
Two observers, myself and a friend Roger Vodicka each observed for 4
hours (8 in tot) for an Teff of 7.65h. I saw a total of 57 meteors,
Roger a total of 51 meteors....<<
Adam, do you plot your meteors? Were your observations during evening hours,
morning hours or mixed? I don't remember your location...Australia maybe?
Adam>>Please also note, it is standard procedure to record a meteor as half
of
each of a radiant if the meteor intersects both radiants like the
Taurids and the angular velocity id acceptable.<<
Is this a standard procedure from your local meteor organization? I believe
Rainer once mentioned something to the effect that you should choose one or
the other. That is make it your best guess. Anyhow, this is what I do. The
Taurids are murder for me to determine which radiant any particular meteor
belongs to. Quite often the meteor and the two radiants line up and it's a
real guess. Sometimes it becomes a matter of which shower is the most active
on any particular date that I choose when they line up. Like now the S.
Taurids are most active. The questionable alignments will favor the S.
Taurids. Later in the month I will favor N. Taurids if need be. The bottom
line is, I don't split up shower membership. For meteors that are close to
the radiants, it becomes a little easier for me to decide. I take into
consideration how long the meteor path is when it passes thru two radiants.
