                        GIACOBINID METEOR SHOWER

        There is a possibility that the Giacobinid/Draconid meteor shower
may put on an enhanced display this year on October 10th.  This shower
should be monitored for any unusual activity.  From a historic note one
should look up the paper, "Giacobinid Meteor Spectra", by Peter M. Millman,
in the August 1972 JRASC, Vol.66, pp.201-211. (Journal Royal Astronomical
Society of Canada)
        To summarize, Peter Millman secured 21 spectra from the 1946 shower
with two objective prism spectrographs.  Weather prospects in Ottawa did not
look good, so Peter, through the cooperation of the RCAF, had a DC-3 put on
alert to take him elsewhere should the weather not cooperate.  Sure enough,
it was cloudy in Ottawa so the RCAF flew him to North Bay just in time to
set up his spectrographs for the meteor storm.  This classic paper showed
that the meteors from this shower were very fragile and fragmented at
abnormally higher altitudes than other shower meteors.
        Unfortunately, this year a bright moon will interfere with
observations but one can still conduct observations in the early evening
before the moon starts to be a problem.  Let's hope we have a good shower!
