(meteorobs) Aftermath?

[Terry Johnson]

Esko, so far as narrowing down the radiant is concerned, I can tell you that
each of the three Delphinid candidates I saw appeared to point back to an
area between epsilon and beta Delphinus (the tail of the dolphin).  They had
semi-long paths, so tracing back was rather easy.  I have no photographic or
video proof of this, so just my visual report.

 

Also, each one I saw occurred between 0700UT and 0815UT.

Hi all,

This prediction was based on three special things. One is that an outburst
really happened in 1930, which most probably is true.
Secondly it is based on the assumption that this was of a long period
nature, a few hundred years in minimum. There is no actual knowledge on this
and this is only based on the fact (above) of an unexpected short lived
outburst that are typical to long period outbursts ( of one revolution
trail).
Thirdly this is based on the derived radiant. If the radiant derived from
the visual observations in 1930 is too much in error, then also the
prediction would fail (most probably would not appear or wery weakly only,
definite time error is not probable). This case however is not especially
sensitive to minor errors in this.
It is now my opinion that this is not of long period, maybe of Hallye type.

I just read in meteorobs on increased radio rater. Maybe this is a GDE
outburst. If this really is, then it could be a non modelled outburst fron a
Halley type comet maybe.
Secondly, I am especially interested on the fireball that Thomas Ashcraft
captured and told he expects to be a GDE. If this is, then hopefully some
improvenemt to the radiant direction can be achived.

I am curious; what is the next step in meteor orbit modeling after an
apparent failure, like that of the GDEs to 'burst out' or perhaps even to
'shower?'  What can the modeler do?  What about amateurs' roles?
 
Thanks.
 
Rich
